The F5 Data maps I post as well, is another out of pocket expense (monthly subscription). Updates to software (weather related), and costs for my domain name are also out of pocket to me.

Good day everyone!
In case anyone is wondering, my winter weather discussions only cover from the central U.S., and eastward. With that said, the 12Z model runs were not complete as of time of analysis and distribution, so all information is based mainly on the 06Z run of the global and regional models.
The current snow in progress should be exiting extreme northern MN. and northern Great Lakes by this evening, then returning to northern MN. / WI. by Tues. morning, then over a portion of MI. by Tues. evening.
Snowfall should be entering the Dakotas by very early Wed. morning, and continue to move eastward, into the upper Midwest (MN, WI, and MI) by Wed. afternoon. I am looking for lake effect snow by Thur. morning, affecting MI., and a small portion of northern NY state. As this system progresses east, snow should then extend into much of NY state, southward into western PA., into OH., and portions of W. VA., and KY. by Thur. evening.
A Gale Warning is currently in effect for the Great Lakes.
Based on analysis of the global and regional model 1000-500 mb thickness charts, with temperature overlay, I expect frigid temperatures to keep a grip on most of the CONUS for at least the next 4 days, before modification takes shape. The following are temperature profiles from the various models for 24 hours out in the forecast:
Based on forecast snowfall accumulation maps form the global models, total snowfall accumulations do not look significant over the next 5 days.
PLEASE!…REMEMBER YOUR PETS…if it’s too cold for you, it’s probably too cold for your pet, so keep your animals inside.
I will not have an update tomorrow, as work calls.
Have a blessed day!
