.DISCUSSION...
Issued at 329 AM CDT Wed Jul 17 2024

Based on a few observations and hints of it on satellite, added
patchy fog for a part of the northwest through the early
morning hours. Overall, suspect most of this fog is very shallow
in nature with very limited coverage. Any fog should rapidly
dissipate after the sun rises.

Not a lot has changed overall. A west CONUS ridge will continue
to ever so gradually slide eastward today and amplify a bit
more. This will keep the area in northwest flow aloft with the
southwest experiencing WAA. Enough of this warmer air is
expected to mix to the surface to bring the return of
near-average temperatures (low to mid 80s) this afternoon in
the southwest, while the rest of the area remains below average
in the 70s. Conditions will remain mostly dry today. However, a
few popcorn showers are once again not totally out of the
question this afternoon, though confidence of occurrence is
very low.

By Thursday, summer will return to the area sans vengeance as
the ridge establishes more influence over the state. This will
result in near-average highs in the low to mid 80s for all but
the southwest, where above average highs are progged to reach
the low 90s. For Friday through the weekend and into early next
week, near-average highs in the 80s are expected to prevail most
everywhere most days. Low NBM 25th/75th percentile spreads
suggest confidence is rather high in this solution.

Embedded weak shortwave energy within northwesterly flow
aloft may bring the return of precipitation Friday through
Saturday. Nothing looks real organized at this time and current
chances range from around 20 to 40 percent Friday
afternoon/evening and around 20 to 30 percent Saturday
afternoon/evening. With a lack of decent shear, and as
supported by CSU Machine Learning, severe weather chances seem
very low at this time.
