Area Forecast Discussion
National Weather Service Wilmington OH
726 PM EDT Thu Sep 22 2016
High pressure will remain across the region through Friday. A weak
cold front will move into the area Saturday...stall near the Ohio
River and then lift back north early next week.
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
Some cirrus will spread across the region overnight. But this
should have little if any effect on radiational cooling
conditions. Winds will become light again. Lows will be slightly
warmer than last night but a bit cooler than guidance.
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
High pressure will remain across the region for another day. There
will be some mid to high clouds...but still a good deal of sun.
Temperatures will be near persistence.
A weak cold front oriented east-west will sag south. Wind shift
will move through Friday night with any change in airmass lagging
behind and not moving into the area until Saturday. Forcing is
meager but 12Z models have enough of a signal to warrant slight
chance PoPs in the Whitewater and Miami Valleys Saturday
afternoon. Expect the front to stall near the Ohio River. This
front will lead to a pretty good gradient in temperatures from
north to south both Saturday and Saturday night.
.LONG TERM /SUNDAY THROUGH THURSDAY/...
Models are in agreement on keeping Sunday dry, however there is
still quite a bit of model variability beyond this time. At this
time Monday and Wednesday look to be the best chance for
precipitation. Limited any precipitation chances to the chance
category until there is better resolution and confidence in one
solution. Models are trending cooler for later portions of the
long term. Went with a model blend for the Monday through Thursday
time period. Sunday and Monday will be the warmest days with cooler
conditions after that time.
.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --Surface high pressure will hold across the area again through the
TAF issuance allowing for mostly VFR conditions. The mostly calm
winds and light east winds will make fog likely at KLUK. During
the day Friday mostly light winds and some cirrus will be all to
speak of as high pressure remains in control.
OUTLOOK...No significant weather expected.
