Thunderstorms are not forecast through tonight across the contiguous United States. ....20z Update... The previous forecast remains on track with no changes required. Recent observations and latest guidance continue to suggest very limited thunderstorm potential. See the previous discussion below for additional details. ...Moore.. 02/17/2025 ..PREV DISCUSSION... /ISSUED 1012 AM CST Mon Feb 17 2025/ ....Synopsis... A cold, continental-polar airmass is in place across the much of the Lower 48 today due to a 1045-mb surface high centered over the ND/Canada border region. Dry/cool offshore flow this morning has led to tranquil conditions across much of the Eastern Seaboard and Gulf coastlines. As a cold front pushes south across the central into the southern Great Plains, low-level flow will veer across the northwest Gulf Coast with onshore flow beginning mainly tonight. Thunderstorm potential in this region will be negated by the onset and limited duration of moisture return into the TX Gulf Coast. Cool/dry conditions will be pervasive across much of the CONUS. $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
