.DISCUSSION...

Tuesday morning is expected to be rain-free, with precipitation
chances increasing during the afternoon as a cold front approaches
from the west. Smoke dispersal starts out poor during the early
morning and improves to fair by late morning as mixing heights
increase to 2000-2500 ft by Noon CDT. Relative humidity remains
high throughout the morning due to dewpoints in the low to mid
60s.

Showers and thunderstorms will arrive from the west by early
Tuesday afternoon along a cold front. Some of the storms could be
severe with the potential for hail up to 1 inch in diameter and
wind gusts up to 60 mph. The window of severe weather will
primarily be between 2-5 PM, but lingering showers and non-severe
thunderstorms will persist into at least the early evening. Rainfall
amount forecasts have increased, ranging from 0.75-1.25 inches,
most of which will occur with the more robust storms in the
afternoon. Non-thunderstorm winds out of the southeast quickly
ramp up to around 10-15 mph with gusts of 20-25 mph from late
morning into early afternoon ahead of the storms/cold front and
quickly turn westerly behind the front. Humidity values will
remain elevated through the day Tuesday due to increasing
dewpoints in the morning, as well as showers and storms in the
afternoon and evening.

Thunderstorm chances end by mid-evening, with rain chances ending
in the late evening prior to midnight. Winds turn light at 5-7 mph out
of the west to southwest from mid-evening into Tuesday night with
skies becoming mostly clear overnight. The minimum temperature
dips to the low-50s by early Wednesday morning.
