Winter Storm will create a mess across North Texas

Tuesday Evening Weather

Catastrophic fire weather across Southern California with 80-100 mph+ gusts increasing into the overnight and early Wednesday morning.

HRRR wind gusts next 18-hours

The surface pressure pattern favors strong offshore flow already, but the addition of a cut-off mid-level trough with counter-clockwise circulation is ramping up winds to a much higher level.

High Pressure > 1045 mb across Northern Plains

700 hPa Winds show strong low-level counterclockwise circulation centered over Yuma, Arizona.

And, the 500 hPa upper-level trough anomaly is situated right there … all of these features are perfectly aligned to maximize wind gusts from the SoCal mountains/hills down to the beaches.

Rain during last 6-months

Not much … and probably little relief for the next 10-14 days at least.

North Texas Winter Weather Threat | Thursday

ECMWF HRES 18z and its ensembles have remained consistent with temperatures cold enough (33°F) in Dallas-Fort Worth for up to 6” of snowfall with 0.7” QPF.

Much heavier QPF and rainfall is only 50-100 miles to the SSE of DFW, with > 2.4” around Houston.
