Today will see another day of unseasonable warmth just ahead of a
cold front that will swing through the area later in the afternoon.
925 hPa temperatures won`t be as high as yesterday, but most areas
should still be able to rise into the middle to upper 70s with a
couple of 80 degree readings possible across central MO. Increasing
isentropic lift ahead of the front should bring an increase in clouds
through the afternoon, and possibly a few elevated showers or weak
thunderstorms although these will have to battle a very dry low-
level airmass just off the surface.
Airmass ahead of this evening`s cold front will be strongly capped
and anything that develops before 03Z or so will have to come from a
highly-elevated and weakly unstable layer above 850 hPa. This should
keep any precipitation fairly isolated in nature until the front
makes it into central Missouri later in the evening. These areas will
have more time for capping to erode although instability and
moisture will remain fairly weak. Therefore any storms that do
develop out that way should stay scattered in nature with strong
storms or heavy rain looking unlikely.
Weak northwesterly flow behind tonight`s front will bring
temperatures back to seasonal averages through the remainder of the
week. May need to watch for a light frost across northwest MO Tuesday
night with a low-level ridge axis and light winds setting up over
that area. Otherwise no frost/freeze chances on the horizon until
Friday night at the earliest, and even that is trending a bit warmer
than previous forecasts.

VFR through the period. Gusty southerly winds may continue into the
morning hours before relaxing some with the approach of the surface
trough. Otherwise, frontal passage will provide wind shift and may
bring low-end VFR clouds and scattered showers by late afternoon.
Conditions will improve by early evening.
