Very cold morning after serious radiational cooling along the wash overnight - low here at house dropped to 20F. MesoWest plot above shows morning lows today with most of metro area below freezing.
The 12 UTC WRF forecasts from Atmo indicate increasing east winds during next 30 hours or so - above forecast is from the WRF-NAM and is valid at 11:00 am MST tomorrow, the 24th. However, the forecast from the WRF-GFS indicates a significant wind event at the Mt. Hopkins beginning by evening and increasing during the night. Below is the forecast skewT at Sonoita at midnight tonight. If this forecast verifies, I would expect gusts at the RAWS site to reach 50 to 60+ mph, before decreasing during the day tomorrow.
