.DISCUSSION...
Issued at 218 PM EDT Mon Apr 8 2024

- Tonight

We hope you all have a wonderful viewing of the total solar
eclipse this afternoon! cloud cover will remain at 10-30% this
afternoon, although scattered cirrus clouds shouldn`t impact
viewing experiences too much this afternoon. The next
opportunity to see a total solar eclipse across much of the US
won`t happen again until 2045. We`ve been experiencing mostly
sunny skies this afternoon as dry air works across much of the
Midwest. Clouds will increase again overnight from south to
north with mild lows in the upper 40s to low 50s.

- Tuesday Through FRiday

Highs will be in the upper 60s to low 70s again on Tuesday thanks to
WAA and southwesterly winds. An active pattern returns this week; A
cold front will move through the area Tuesday evening, bringing
slight chances (20-30%) for rain southeast of Fort Wayne Tuesday
night into early Wednesday. A few sub-severe thunderstorms are
possible as well. More recent runs of the NAM and RAP have trended
towards keeping the more widespread rain south of the CWA in
southern Indiana and Ohio..

A strengthening area of low pressure will lift through the mid
Mississippi and Ohio River valleys Wednesday night through Thursday,
leading to widespread rain chances and a few embedded thunderstorms
too. PoPs increase Wednesday evening (up to 80%) and persist through
the morning on Friday. A soaking rain is likely for many with WPC
QPF forecasting 1.5 to 2 inches across our CWA by Friday morning.
This will likely exacerbate river and stream flooding once again, as
many areas waterways have just come down from heavy rainfall last
week. Highs Wednesday through Friday will be in the mid 50s to mid
60s.

- Saturday and Sunday

The weekend is shaping up to mainly dry, with highs rebounding into
the low 70s! A slight rain chance exists for Sunday afternoon (20-
30%), but otherwise, expect a sunny and warm spring weekend!

.AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/...
Issued at 149 AM EDT Tue Apr 9 2024

A mid/upper level front will bring good deal of high clouds
across northern Indiana this morning. Otherwise, light south
winds will continue through the remainder of the early morning
hours. Surface trough across the Mid MS Valley will push
eastward today as stronger upper vort max lifts northeast across
southeast Ontario by late this afternoon. This will allow for
some increase in low level height gradient and the potential of
some southwest gusts into the 15 to 20 knot range today. Better
pre-frontal moisture transport should largely just bypass KFWA
to the east across NW Ohio. With better instability axis likely
being situated east of KFWA, will continue with a dry forecast.
Post-frontal winds become light northwest for tonight.
