SNOW FOR SOME TONIGHT...
A fast moving disturbance will spread snow back into the NW half of my area overnight. Accumulations should range from about 1/2" in the Quad Cities to as much a 3" near Waterloo. The NWS has the 1" line running NW of Ottumwa to West Branch, to Savanna, and on to Freeport. The further northwest you go the higher the totals.
While there are no advisories in effect slick travel is likely especially where an inch or more falls. This will be a fast mover and the snow will end from SW to NE around midnight to 2am. It should begin soon in the western parts of my region if it has not done so already. Here's the latest radar.
One other factor to consider, especially in the southeast where the snow will be light is the possibility of some freezing drizzle. A light glaze is possible that could generate some issues despite the very light nature of the precipitation.
These are the snowfall forecasts, the raw model output...
The EURO
The GFS
The 3k NAM
With the fast movement, the disturbance will be long gone by tomorrow. Enjoy your evening...TS
STILL 2 SPOTS AVAILABLE FOR WEATHER SCHOOL. A GREAT BUNCH OF FOLKS COMING IN AND SOME TERRIFIC CASE STUDIES YOU WILL ENJOY, ESPECIALLY 2011, THE YEAR OF THE TORNADO. AN IN DEPTH LOOK AT THE SUPER OUTBREAK OF APRIL 27TH IN ALABAMA AND THE JOPLIN TORNADO WHICH TOOK THE LIVES OF 160. YOU WANT TO LEARN WEATHER, YOU WANT TO BE HERE. GET THE DETAILS BELOW...
TSwails.com is offering a very special and unique opportunity to learn first-hand the ins and outs of weather forecasting with one of the best meteorologists in the Midwest along with his team of expert meteorologists.
That’s right… You want to forecast right along with Terry Swails, well now you can. He’s teaching weather with TSwails newest program called WEATHER SCHOOL. The opening bell rings this January and you can be a member of the very first graduating class. The one-day forecasting seminar for weather enthusiasts will be held at his home in January. It’s not your typical run-of-the-mill school. There will be no tests, but Terry, Rebecca, and Nick will cram your head with so much knowledge, it’ll be spinning like a tornado before the day is over.
You want to know the essential online sites to use for models, radar, and the basic weather tools? DONE! You want to understand the structure of models and the role they play? DONE! You want to be able to construct forecasts from the ground up? DONE!
WEATHER SCHOOL will be presented in a seminar-type format where you'll have the ability to ask questions and dig deep. You’ll get the scoop on data acquisition, model analysis, severe weather, and actual forecasting from the big dog himself, T. Swails. With 43 years of experience and an uncanny ability to break the science down, you’ll open the door to forecasting like never before.
Along with the head master T. Swails himself, meteorologists Rebecca Kopelman and Nick Stewart of KGAN TV will be there to lend their knowledge and experience to the discussion. It will be fun, informative, and factual! This is the day for you to see, feel, and experience what it’s like to be in the hot seat of a meteorologist.
The seminar will be held January 25th and will last from noon until 5:00pm. We have limited seating and the cost is $99 dollars per person. A catered lunch will be provided. Again..not a lot of seats so reservations with a pre-payment are required. Sorry, no refunds. If there’s enough interest, a second session will be added in early February.
