.DISCUSSION...(This evening through Saturday)
Issued at 243 PM CST Sat Dec 5 2020

As expected, today has been a bit cooler and more breezy a than
yesterday, but the entire area has still managed to reach the 50s
under completely clear skies. Aloft, the area remains in very
amplified north to northwesterly flow, with a broad trough over
the eastern CONUS. A shortwave will pass to our east tonight into
Sunday morning. Temperatures tomorrow may be just a degree or two
cooler behind this trough, but winds should also be less breezy
than today.

Ridging then takes hold for the beginning of next week and
forecast highs for the first half of next week have continued to
trend upward. Some models show temperatures reaching the mid 60s
across nearly the entire area by Wednesday. Therefore, I went with
the warm side of guidance, especially for Tuesday-Wednesday, and
I would not be surprised if a few spots even approach or briefly
reach 70 degrees.

These warmer temperatures bring a bit of an uptick of fire
danger. Minimum RH values are forecast to be around 20 percent for
the western half of the forecast area each afternoon from Monday
through Wednesday. For now, it appears that the windiest day will
be Monday, but even then, we should remain just at or just below
20 MPH. Therefore, we have just mentioned the potential for near-
critical conditions in the HWO.

A cold front is expected to move through the area Wednesday
evening and overnight, bringing a return of more seasonable
temperatures for Thursday, and especially for Friday. Ensembles
still show some potential for rain/snow late Friday through
Saturday as a deeper trough moves through, but timing and location
are still all over the place. Because of this uncertainty, our
forecast remains dry.


.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Monday)
Issued at 503 PM CST Sat Dec 5 2020

Dry weather with VFR conditions are forecast for this TAF period.
Any clouds passing through are expected to remain in the mid-upper
levels. Not much change expected as far as winds go, which will
remain northwesterly thorugh the period. Speeds will top out
around 10 MPH.
