.SHORT TERM...(Today and tonight)
ISSUED AT 320 AM CDT Tue Mar 19 2019

No significant changes to the weather today, except a slight
increase in the sky cover as cirrus clouds began to overspread the
region early this morning. Temperatures will once again climb to
the low 50s today, after another chilly start to the day.

A wave will develop in the central Plains this morning and arrive
into the region during the overnight.


.LONG TERM...(Wednesday through Monday)
ISSUED AT 320 AM CDT Tue Mar 19 2019

A Low pressure system in Canada will dive into the Great Lakes
region Wednesday. The cold front associated with the Low will
slide in on the back side of the wave, giving it a push out of the
Midwest Wednesday afternoon.

Wednesday will be a wet day, however it will be a light rain
event, with forecast QPF values ranging from 0.20-0.40 in most
locations. As a weak frontal boundary slides through, it will move
rainfall into the Ohio Valley Wednesday evening. Behind the front,
temperatures will not be affected much, as warmer air is filtered
into the region from the southern Plains.

Most models have another weak vort max falling through the upper
Midwest Wednesday night into Thursday, which could bring
sprinkles to the northern portion of the CWA Thursday morning.
However, at this time I left the mention out of the forecast due
to the minimal chance.

High pressure ridge will build back into the region for the end of
the week, with sunny skies during the day and clear skies
overnight. Temperatures will continue to increase into the
weekend, as highs will climb to the 60s Saturday and Sunday. High
pressure dominates into the weekend, but another system pulls into
central Illinois Sunday.


.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1149 PM CDT Mon Mar 18 2019

As high pressure departs to the east tomorrow, mid and high clouds
with thicken across the area. Increasing southwest winds will draw
moisture northward into central IL. Spotty showers may develop
west of PIA to SPI by mid to late evening. Despite the chances of
precipitation, VFR clouds are expected Tuesday evening.

Winds will diminish and become more southerly Tues evening as
shower chances increase.
