.DISCUSSION...
Despite full sunshine today, temperatures have struggled to reach
the freezing mark in many locations due to much of the snowpack
left over from yesterday. As a result, it won`t take much to fall
back into the teens overnight under clear skies and calm winds.
Therefore, a Hard Freeze Warning is in effect again tonight from
9 PM to 9 AM Thursday. Also, can`t rule out some outlying and
more rural areas falling into the upper single digits overnight.
The good news is we`re almost done these bitter cold temperatures
after tonight with a gradual warming trend taking shape for the
rest of the week. With southerly winds returning, daytime highs
on Thursday will rebound into the lower end of the 40s while
overnight lows fall back into the 20s over much of the area.

The more significant warming trend will come Friday but especially
this weekend as southerly flow increases. Highs will average near
50 degrees on Friday and then climb into the 60s on Saturday with
a slight chance of showers entering the picture Friday night into
Saturday with an embedded shortwave ahead of our next cold front.
The much more significant rain chances will come Sunday through
Sunday night as the cold front enters our region. Temperatures
ahead of the cold front may top 70 degrees in some areas Sunday
afternoon before widespread showers and isolated thunderstorms
will spread across the region along and ahead of the front with
rainfall amounts averaging between a half inch to near one inch
through Monday morning. The threat of severe weather still looks
minimal at this time, but we will continue to monitor potential
for any stronger storms with this system. The front will exit the
area around daybreak on Monday with cooler and drier conditions
to start the new work week. Temperatures will average very near or
just slightly above seasonal averages through early next week
behind the front.
