Chance For Sprinkles Tomorrow/Friday


View of East Mall at the University (from Jim Wyant's office) shows that it's nearly deserted at a bit before 7:30 am MST this morning.


A 500 mb short wave will swing across Arizona late tomorrow and Friday - forecast above from 06 UTC GFS is valid at noon on Friday the 27th. Below is the forecast of 850 mb winds and precipitable water valid at the same time. Narrow band of higher PW has already moved well south and east of our area, making for a very moisture-starved system.



Forecast above is for total precipitation through 5:00 pm on Friday, and below shows 09 UTC plumes for temperature at the airport (from SPC webpage). 

Basically the forecasts indicate periods of gusty winds (no graphics shown), with a chance for sprinkles and cooler temperatures tomorrow and Friday. Final system of month will come by at start of next week, but it will likely be another moisture-starved "event."
