Dave Murray’s Latest STL forecast and weather disco…WEDNESDAY…February 25, 2015

*** Two systems come into play over the next 24 hours..a back-door cold front followed by a new Clipper with a fast snow. We will be a little colder today and then more big cold Thursday and Friday.***

WEDNESDAY:

Increasing clouds and a little colder
WINDS: East 5-15 M.P.H.
HIGH: 32 DEGREES

WEDNESDAY NIGHT:

Clouds…snow developing around midnight…moving in from the north…cold
WINDS: East 5-15 M.P.H.
LOW: 19 DEGREES

THURSDAY:

Snow ends in the morning…otherwise…lots of clouds…snow…an inch or less… up to two inches 50 plus miles to the north and northeast of metro STL
WINDS: Northwest 10-20 M.P.H.
HIGH: 25 DEGREES

Bitter cold for Friday.

THE WEATHER DISCO:

The next cold front drops in…a back-door cold front arriving from the north/northeast first thing in the morning…aloowing a little colder air to sweep in…lets go with a dry front. Then riding along the front will be a fast moving and weakening clipper for Wednesday night and Thursday morning…a fast hit of dry snow…about an inch or less for metro STL…a little more…up to 2 inches…50 plus miles north and northeast of mtro STL. Looking like enough to create some slick roads for the Thursday morning rush….especially with very cold temperatures in place. Just cold and dry for Thursday afternoon into Saturday. At that point…Saturday night…snow will develop and break-out of the region…expect some accumulations at this point in time…then going to a mix of rain and snow during the day on Sunday… a little break with another wave of rain and snow for Monday night and Tuesday…so this late weekend and early next week system will be an extended winter weather event. A long way to go and concepts will be flipping around…typical of this winter…so lets stay tune…get the clipper out of the way and then we can move forward….but certainly an unsettled run of weather on the way. The questions will be how hard the cold air digs in and how much moisture comes into play.
