.SHORT TERM...(This evening through Tuesday)
Issued at 300 PM CDT Mon Jul 8 2019

Another day, another round of scattered afternoon showers/storms.
Today's activity initiated where slightly better low level
convergence existed this morning, but now outflow boundaries are
serving as the main triggers for storms. The air mass is very
similar to the past couple of days and expect the activity to die
down gradually this evening. Drier low level air up in our far
northeast cwfa will likely keep that area dry today/tonight.

An upper level short wave ridge over our area now will shift off
to the east for Tuesday and think coverage of storms will be
slightly higher. Higher pwats of around 2.00 inches are expected
and may support an uptick in rainfall amounts, especially over the
eastern cwfa as a subtle shortwave moves through.

Heat index values will reach just over 100 deg F over the western
and southwestern cwfa on Tuesday. That is below heat advisory
criteria, but creeping up a bit from what it has been.

.LONG TERM...(Wednesday through Monday)
Issued at 300 PM CDT Mon Jul 8 2019

Wednesday: Finally a change in the pattern as a shortwave moving
through the Dakotas and Midwest push a sfc front through the
region on Wednesday. Weak vertical shear and what looks like
highly veered sfc winds ahead of the front (limiting low level
convergence) looks to limit storm coverage/chances and
organization. Given the moderate instability and a fropa the SPC
marginal risk looks reasonable/prudent.

May have to watch temperatures/humidity during the day Wed.
Our forecast database has 100 to 105 deg F heat index values in
the afternoon. Temperatures should cool off Wednesday night.

Thursday-Saturday: Looks rain free. Lower humidity is expected
with cooler temperatures late in the work week, especially at
night. As an upper ridge begins to build back in from the west
over the weekend we should see a warming trend, but nothing
unusual for July.
