Changes For Last Part Of Month?



Thin cirrus with some color before sunrise this morning. Down at bottom is view of the Gateway Arch (St. Louis) in morning snow - looks like a couple of barges on the river too. Weather this weekend will be concentrated in central and eastern US.

The 06 UTC run of the WRF-GFS model is forecasting gusty, east winds developing today - forecast above valid at noon today.

Longer range forecasts are holding out hope for for a change to stormy/showery weather for last third of January - note that there has been no precipitation here yet in 2022. Forecast above is from 00 UTC WRF-GFS at Atmo indicating a nice precipitation event for southeastern Arizona by 5:00 pm MST on the 22nd (i.e., a week from today). Below is 00 UTC GFS forecast for precipitation through 11:00 pm on the last day of month. These forecasts are fairly far out, so we will have to watch to see how the situation evolves - remember that the last event forecast for mid-week this week just fizzled away.
