High pressure and a drier airmass will be in place across the
region through Tuesday. A chance of showers and thunderstorms
will return Wednesday night into Thursday night as a cold front
moves into the area. High pressure and dry conditions will then
build back in for the weekend.
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Surface high pressure centered over the middle Mississippi River
Valley will build east into the Ohio Valley today. Mainly clear
skies this morning will give way to few/scattered cumulus clouds
by this afternoon. Highs will be similar to Sunday`s readings,
ranging from the upper 70s to around 80.
.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/...
The center of surface high pressure will move slowly east toward
the Atlantic seaboard tonight into Tuesday. Surface ridging will
continue to extend westward into the Ohio Valley. Mainly clear
skies tonight with light to calm winds will result in idea
radiational cooling conditions. Lows will fall into the lower and
mid 50s. Slight airmass modification under mostly sunny skies will
allow temperatures to warm into the lower 80s by Tuesday
A mid level ridge will build over the Gulf Coast States through
the end of the week. As it does, the mid level flow over the Ohio
Valley will transition from southwesterly to more of a zonal
pattern. Initially, some weak short wave energy will lift
northeastward across the Great Lakes Wednesday into Thursday. It
looks like a weak warm front will also lift north across the area
through the day on wednesday, but forcing with this boundary
remains fairly weak. As a result, will maintain a dry forecast at
this point on Wednesday. We will begin to moisten up Wednesday
night into Thursday as a weakening cold front moves southeast into
our area. This will lead to an increasing chance of showers and
thunderstorms later Wednesday night into Thursday. It will become
warmer and more humid through the period ahead of the weak cold
.LONG TERM /FRIDAY THROUGH SUNDAY/...
The threat for showers/storms should taper off heading into
Friday as the weak front washes out across our area. Dry weather
is then expected for the weekend as the mid level ridge builds
northward into the Ohio Valley. Highs Friday and Saturday will be
in the lower to mid 80s, with mid to upper 80s becoming more
prevalent by Sunday.
.AVIATION /10Z MONDAY THROUGH FRIDAY/...
