12:30 PM update from the Storm Prediction Center continues to put West Michigan in the slight risk area for severe storms:

It's still a wait-and-see situation for our area, as we are monitoring an area of storms coming out of Wisconsin, as well as keeping an eye on anything that could pop locally this afternoon.  As has been the case much of the week, the fuel is there, but we're waiting for a spark to trigger the storm development.  Our RPM computer model has a batch of storms popping by mid-afternoon along and east of US-131, in addition to some of the Wisconsin storms trying to move in.  However, it still keeps only those hit-and-miss storms around West Michigan before drying us out this evening. - JS

Wanted to quickly point out that West Michigan falls in the risk area for severe thunderstorms at a couple of points later this week.

Thursday's outlook:

Saturday's outlook (Saturday is marked as D4):

A lot will depend on the timing of the cold fronts that will move through the region on both of these days.  While there will be a bit more warmth and moisture "fuel" to work with Thursday, the cold front on Saturday currently looks to be the stronger of the two.

Best case scenario- Thursday's front clears the area before storms develop in the afternoon, and Saturday's front holds off until late night/early Sunday.

Worst case scenario- The first front hangs around through Thursday afternoon, allowing severe storms to the south of the front; Saturday's storms arrive in the early evening when temperatures are near their warmest.

As always, we'll keep you posted! - JS

Air Quality Action! Day

| | Comments (0) | TrackBacks (0)
It's the first Air Quality Action! Day of the season in West Michigan, as temperatures will climb into the low 90s with heat index values in the mid to perhaps even upper 90s.

Some tips from the Michigan Department of Environmental Quality:

"Everyday ... and especially on Action! Days, people make voluntary choices that reduce the air pollution emissions that can lead to poor air quality.

MORE CLEAN AIR CHOICES:
  • Walk, bike, or consider using public transportation where possible.
  • Maintain your vehicle. A well-tuned car emits less pollution.
  • Drive at moderate speeds and avoid "jack rabbit" starts and stops.
  • Avoid topping off your tank when refueling -- it leads to spills.
  • Defer using other gas powered lawn equipment on an Action! Day. Small engines usually have inefficient emission-control systems.
  • Avoid "drive-thru" windows at fast food restaurants and banks on Action! Days.
  • Tele-conference instead of driving to meetings.
  • Defer / avoid using oil-based paints, solvents, and cleaners.
  • Save electricity. Adjust air conditioner temperature a few degrees higher. Turn off appliances & lights when not in use.
  • Purchase energy efficient appliances and products.
REMEMBER, YOUR ACTIONS DO MAKE A DIFFERENCE!

HEALTH TIP: People sensitive to air pollution should avoid prolonged, strenuous work or exercise when air pollution is elevated. Consult your doctor for specific health advice."

Here is more information about the Action! program.

Lots of weather!

I just received a press release from the National Center for Atmospheric Research about a new study that discusses the importance of weather forecasts to the American public.  It's good to know that the demand for weather information doesn't really change, even though the ways in which people get their information has shifted dramatically over the years.

According to the study, survey participants receive weather forecast information about 3.8 times a day.  Of course, if any viewers of FOX 17 Morning News were included, the results would be skewed since I give 21 different forecasts during each show!  And that's not including material for the Web and local radio stations.

The full text of the press release is below.  Stay cool the next couple of days! -JS
--------------------------------------------------------

BOULDER-Close to 9 out of 10 adult Americans obtain weather forecasts regularly, and they do so more than three times each day on average, a new nationwide survey by scientists at the National Center for Atmospheric Research (NCAR) has found. The value Americans place on these forecasts appears to be far more than the nation spends on public and private weather services.

The research is the first comprehensive study of its kind to examine how the public perceives, uses, and values weather forecasts. Funded by the National Science Foundation, NCAR's sponsor, and the National Oceanic and Atmospheric Administration, the study appears in the June issue of the Bulletin of the American Meteorological Society. 

U.S. adults obtain an estimated 300 billion forecasts each year, says NCAR scientist and lead author Jeffrey Lazo. The study also reveals that most people are generally satisfied with weather forecasts and have fairly high confidence in forecasts with a lead time of one to two days.

"Weather forecasts equate to an enormous volume and multiplicity of information, when you account for the array of forecast providers, communication channels, and the size and diversity of the U.S. population," Lazo says.

Understanding how individuals use day-to-day weather information can help direct the development of more relevant and valuable weather forecasts and warnings by providers like the National Weather Service, he adds.

Gaining a better understanding of people's attitudes and behaviors toward forecasts also provides valuable information to forecasters and emergency managers.

"Better communication strategies can be developed for hazardous weather like hurricanes, winter storms, and floods," Lazo says. "Improved understanding will also help forecasters to communicate forecast uncertainty more effectively."

-----More than three forecasts a day-----

The Internet-based survey, conducted in November 2006, collected information about respondents' weather-related activities and experiences, as well as basic demographic information. Of the 1,520 individuals surveyed, 1,465 (96 percent) said they used weather forecasts.

Of those 1,465, 87.1 percent reported getting a forecast at least once a day on average, while 9.2 percent reported doing so once a day or less on average.

Although the number of forecasts a person obtains varies significantly from day to day, depending on factors like weather events and planned activities, the researchers found that on average survey participants received forecasts 3.8 times a day. These findings, when extrapolated to the total U.S. adult population of 226 million, indicate that Americans receive a yearly total of about 300 billion forecasts.

-----Valuing a forecast-----

The authors cautioned that it is difficult to put a dollar figure on the value of forecasts. However, the researchers asked respondents what they believed forecasts to be worth, presenting them with hypothetical amounts that they were currently paying in taxes and asking if they felt that value was correct, worth more, or worth less than the amount indicated.

Respondents indicated that, on a per-household basis, they would place an average value of about 10.5 cents on every forecast obtained. This equates to an annual value of $31.5 billion. In comparison, the cost of providing forecasts by government agencies and private companies is $5.1 billion, according to the paper.

"Our estimates indicate that Americans are getting a good deal on weather forecasts," says Lazo. "While it's hard to precisely estimate the value of the forecasts, it is clear that there is a significant difference between the cost of forecasts and the value that people place on them."

-----Fascination with the weather-----

Coauthor Julie Demuth, an NCAR associate scientist, says the study also reveals people's curiosity about the weather, with 85 percent of respondents saying that more than half the time they obtain forecasts simply to know what the weather will be like.

"This tells us that people generally have a high level of interest in weather forecasts, regardless of whether they are using this information directly for planning and decision making," says Demuth.

Many people use forecasts for planning specific activities, such as vacations, and routine daily activities, such as deciding what to wear and how to get to work or school. The peak periods for accessing forecasts are the early morning, early evening, and late evening, says Demuth.

The most common source for forecast information is local television stations, with individuals obtaining forecasts 33.7 times per month on average. Cable television and radio are the next most popular sources. Web pages and newspapers were less common sources overall, but both are a daily or more frequent source of forecasts for 27 percent of respondents.

"We should be doing this type of survey every two to three years so we can see what changes are happening, particularly in how people are using technology like mobile phones and the Internet to receive forecasts," says Lazo.

Flooding updates, tornadoes & more

Wow... I sure picked a good week to have vacation scheduled, missing out on severe storms with damaging winds, flooding rains, and tornadoes!

Here's the link to check out the latest hydrograph for the Grand River near Ionia from the National Weather Service.

As of right now, the river has crested at Ionia, and water will slowly recede early this week.  Here's the part that seems a little odd: the Grand River is technically speaking NOT flooding... it is only above what is called the "action stage."  That's basically the level at which there are impacts that people will notice.  Unfortunately, because the Ionia Fairgrounds sit so low along the river, those impacts were VERY noticeable for those attending the Birthday Bash.  Notice at the bottom of the page the list of river levels that affect the fairgrounds; the water really needs to drop below about 15 feet before problems come to an end.  That's expected sometime on Wednesday.

But that's not all!  Somewhat unnoticed amid the flooding rain Friday evening was a series of three tornadoes in southern Allegan and northern Kalamazoo counties.

Here is the link to the National Weather Service's summary of the Friday events.

I even saw a report from Fulton County, Indiana (about 45 minutes south of South Bend) of grapefruit (4" diameter) hail!

Here's hoping the first few days of summer bring us a chance to enjoy some more pleasant weather!

Severe Weather Possible June 18-19, 2009

| | Comments (0) | TrackBacks (0)

As a warm front lifts toward the Michigan/Indiana border Thursday night, we will likely see a complex of strong to potentially severe storms develop along and ahead of the frontal boundry. Large hail and damaging winds are possible along with heavy rain and frequent lightning. The best timeframe for this would be AFTER midnight into Friday morning. A few showers and storms are possible on Friday, but a second round of strong to potentially severe storms may roll through the area Friday night as the actual low pressure area and cold front sweep across the state. Take a look at the Storm Prediction Center (SPC) outlook for severe weather the new two days. West Michigan is in a "slight risk" both Thursday night and Friday night. While the better chance (moderate risk) of severe storms remains both south and west of the area, we may still some of these storms reach West Michigan with 60 mile per hour winds, and/or one inch size hail along with heavy rain. Stay tuned to later forecasts and make sure to check our FOX 17 "Weather Page" and "Alert System" for any forthcoming watches, warnings, or advisories.

Digital Transition Dilemma

| | Comments (0) | TrackBacks (0)
As you might have heard, there's a little deal happening today involving the complete upheaval of the method of transmitting television signals.  No big whoop for a guy who works at the TV station, right?  Well, I'm ending up as one of the people who will be impacted by the switch to digital transmission.

My family recently moved, and I haven't had the cable service set up yet.  When the Red Wings played on Tuesday, I was able to plug in the old TV and hook up the rabbit ears.  But now, that analog signal isn't available, which might mean that I won't be able to watch Game 7 tonight!!!  I do have one digital TV, but the indoor antenna doesn't get all the local stations.  So, I have to test it out today before the game.  Anybody want a meteorologist over to watch hockey tonight? :-)

Finally, in honor of the digital transition, I've converted the 7-day Forecast to all-digital as well.  Remember that "digital" data consists of a stream of information in binary code, essentially a series of "1"s and "0"s, much like used in a computer.  It's fairly easy to convert any number to binary format.

So, the high temperature forecast for the next seven days would look like this:

Friday- 1001010
Saturday- 1001000
Sunday- 1001011
Monday- 1001110
Tuesday- 1001100
Wednesday- 1010000
Thursday- 1010010

I used the Decimal and Binary Conversion Tool to figure out these numbers.

Happy (digital) TV watching, and go, Red Wings!!!

Rip Current Awareness Week

I haven't had much time to talk about it on the air this week, but I do want to mention that this week is Rip Current Awareness Week across the country.  The National Weather Service has a good website with information on rip current safety.  This is an important topic as we get into beach season, as a significant proportion of the drowning deaths on Lake Michigan each year can be attributed to rip currents.

Severe Weather Risk 06.08.09

The updated outlook from the Storm Prediction Center was released around 9:00 A.M., and it still includes most of West Michigan in the slight risk area for severe weather later today.

day1otlk_20090608_1300_prt.gif

Despite the fact that the overall risk area has not moved much, there are indications that there's a lower risk of severe storms than had been anticipated in previous outlooks.  The 30% risk area for wind and hail have been downgraded to 15% (click the link at the top for those detailed graphics).  Also, the breaks in cloud cover will be limited later today, keeping the atmosphere more stable than it would be with sun and warmer air.  Still, we could see a few marginally severe storms later.  Stay tuned to FOX 17 for the latest!
