Update...
for 18z aviation.

&&

Short term...
today and tonight.

Going to start out with some isolated valley and bodies of water
fog this morning, but will quickly erode, giving way to a
generally sunny day. High pressure remains in control of the
region and dry conditons are expected through the short term.
Highs will be in the mid to upper 80s with lows in the upper 50s
in the northeast to 60s elsewhere.

16

Long term...
Wednesday through Monday.

Deep moisture advection will begin on Wednesday to our south as a
disturbance moves toward the Gulf Coast. Antecedent relatively
drier air should keep most of our area dry, but isolated
convection is possible across the far southern counties late
Wednesday afternoon into the evening.

Moisture quality is expected to surge on Thursday into Friday
with precipitable water values around 2 inches continuing into the weekend. The
combination of the Gulf disturbance moving inland and westerlies
aloft indicative of a troughy pattern, will lead to enhancement of
convective activity with 40-60 pops each day.

Aviation...
18z taf discussion.

Surface high pressure analyzed over eastern Illinois is helping
to provide fair conditions with north winds becoming breezy at
times, generally between 5 and 15 knots. Expect VFR conditions
through the period with clouds increasing from south to north
tonight and into Wednesday. Low level winds will become light
again tonight and will shift from the southeast at most sites by
early on Wednesday. Chances for thunderstorms and rain will develop toward the end
of this cycle toward midday on Wednesday at mgm and toi but
potential remains too low to mention at either terminal at this
time.

Fire weather...

Mostly rain-free conditions are expected through Wednesday.
Enhanced rain chances and higher humidity will return on Thursday
and continue through the weekend. There are no fire weather
concerns.
