Always bear in mind, forecasts are subject to change, as forecasts beyond 96 hours have the tendency to become less accurate due to changes in information provided by the Global Models, albeit a “general’ idea can be drawn as to an “approximation” of conditions forecast beyond that time out to 120 hours.
Good day everyone!
The coldest temperatures of the season so far, are expected tonight and Friday night across the nation, especially for the south, including well into the Florida Peninsula.
Someone must of made Ma Nature mad, as this pattern pretty much repeats itself again over the next 7 days. This system, like the previous, is a quick mover, and temperatures will quickly modify, especially over the southern tier of states by Saturday. Winter precipitation (snow, ice, etc.) should be clearing the NE and New England areas by Monday morning. However, current model projections indicate another low to develop, north of the Great Lakes over Canada on Tuesday, bring more cold air and wintry precipitation over the Great Lakes and Ohio valley region on Wed, spreading east into the NE and New England states once again, where snow and ice have not let up, lasting into late Wed. evening, possibly into early Thursday morning of next week. Currently, looking out to around 7 – 9 days out, another round of very cold air will head south, however with the freezing line remaining only to about Texas, and the northern third of the Gulf Coast states. It is currently projected these areas will receive snow and a wintry mix of precipitation around the 26th – the 28th.
Of course, given this is out by 7 – 9 days, I will try to have updates as we get closer to that time period.
Boaters and shipping interests should begin to monitor offshore weather, as winds on the eastern portion of the low by Thursday will attain moderate to strong Tropical Storm force.

Thanks Storm, and thanks for reminding us, me, of your “Tool Box”. It is really great! Hey Monty, let us know how much snow you get. We should have snow here due to a weak storm but a lot over “overrunning” of warm air over cold.Snow should start Sat. afternoon, and by midnight, we could have 2-5″, then a change to sleet and rain. Sunday morning could be a “Mess”!
P.S. got down to minus 1 overnight, but the “killer” here, has been the NW winds, 15-25mph., so wind chills easily -10 to -20 below, or more!
Thank you, LT!
Thanks Storm. Stay warm back there. It looks like we’ll be getting another taste of winter…possibly the biggest storm of the season unless it drops South.
