Brisk north winds prevailing over the region this afternoon
following the passage of a cold front earlier this morning.
Upstream observations show gusty winds as far north as the upper
Miss Rvr Vly as the main pressure rise couplet continues to slide
southeast with time this afternoon. Given upstream obs along with
the slow movement of the pressure rise couplet, breezy conditions
will likely continue right into the early evening hours tonight.
Meanwhile, latest satellite shots show a fair amount of clearing
across the area this afternoon which will set the stage for strong
radiational cooling later tonight after winds weaken and high
pressure arrives from the northwest. In fact, we could be looking
at one of the coldest night of the fall season so far as lows
tomorrow morning should drop into the upper teens to lower 20s.

From a sensible weather standpoint, very little in the way to get
excited about this week as high pressure remains in control
through the Thanksgiving holiday. In fact, much of our upcoming
weather will be influenced by building heights aloft as West
Coast ridging breaks down and warm air slides downstream over the
Great Plains through late week. Based on strong model consensus,
today`s fcst continues the warming trend, and low 70s cannot be
ruled out for some areas Friday afternoon as well-defined thermal
ridging extends over the area out ahead of a cold front that
should pass late in the day.

Dry but cooler weather is expected for the weekend as high
pressure builds down the Miss Rvr Vly and northerly winds briefly
return to the area. Highs both days should top out in the low to
middle 50s, however warmer values will be possible by Monday out
ahead of another cold front that is expected to move through the
sometime on Tuesday. With limited moisture however, this passage
should also be dry given latest model solution trends.
