Chaotic Skies This Morning


Chaotic skies over the Catalinas at a bit after 7:00 am MST this morning. Was delayed this morning and didn't get a post done, so this is a quick, midday look toward tomorrow.


Models continue to swing strong 500 mb trough across Arizona tomorrow - forecast above from 06 UTC GFS valid at 5:00 pm tomorrow afternoon.


Water vapor image at 11:00 am today shows a strong dry intrusion, ahead of the low west of California.

Forecast below is for total precipitation though 6:00 am on Thursday morning - from the 12 UTC WRF-GFS run at Atmo this morning. Forecasts look somewhat similar to the event at end of last week.
