Dry Weather Ahead

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

It appears that much of the flurry of activity in our weather is over for a few days as we settle into a long wave trough positioned over the eastern half of the country. This opens the door for primarily dry weather with occasional shots of colder air for the next week or so.

Beautiful Skycam shots this morning from our Alpha Skycam Network. Temperatures on the chilly side with readings generally at or below freezing. But with full sunshine today we should warm nicely into the upper 50s for most locations.

An impulse riding into the long wave trough position will bring a dry front through the area Monday which will drop temperatures once again to around 50 with some locations not getting out of the 40s. But with little to no moisture to interact with, the front will come through dry with perhaps some clouds at best.

Temperatures will be pretty cold Tuesday but rebound into Wednesday. The morning low Tuesday is likely to be in the lower 20s with some spots dipping into the teens.

The upper air pattern flattens on Thursday as a strong short wave moves out of the northern Rockies. That disturbance drops into Oklahoma on Friday and we’ll see the development of a fairly substantial surface low that will move into Ohio as a cold front moves southeastward through the Southeast US. The GFS and ECMWF are in fairly good agreement on the overall idea for the pattern, however, the GFS is somewhat slower than the ECMWF. The GFS places the surface low over Ohio on Friday at midday while the ECMWF puts it over Southern New England. This means our next good shot at rain should come from late Thursday into Friday. Timing to the ending of the rain varies significantly, so we’ll have to be adjusting that in future forecasts. But both models agree that next weekend should be dry with another shot of cold air.

Looking into voodoo country, another wet event seems likely around the 29th of January and the pattern stays reasonably cold looking with the trough fairly well established over the eastern half of the country.

I had the opportunity for a quick trip to Huntingdon, TN, on Thursday. It was quite an adventure as we left Helena around 8 am and encountered significant sleet in western Cullman County which changed to a nice snow event as we got into Lawrence and Colbert counties. Sleet really came down hard enough to produce slush on the Highway 157 and numerous wrecks to go with that. But we drove carefully and finally got into some beautiful sunshine when we reached Savannah, TN. Came back Friday afternoon using the Interstate route, and I like the other route we took up there much better even with some two lane roads. I plan to have the next Weather Xtreme Video posted by 8 am or so on Sunday morning. Enjoy the day and Godspeed.
