Stalled Western Low Means Front A Slow Go...

The trough that brought some rain to the West Coast has moved into the Rockies and stalled over New Mexico.  That has resulted in a SW upper flow from Texas to the Great Lakes with little eastward movement until Friday.  Even then, a surface cold front is not likely to have enough upper support to push through us and bring back the drier, good feel air for the weekend.



Since most of the upper energy will stay to our north and west, the severe weather threat for us has diminished along with the risk for heavy rainfall.



The top graphic is today's severe weather risk with the next being valid for Thursday.  Note how the risk decreases.  Radar only shows some spotty storms and that will be where the rains will stay for tomorrow.



While we have only some puffy clouds, back in Texas are some tall clouds that create shadows (arrow) on satellite views.






The cold front will only stagger to the east tomorrow perhaps getting close enough by Friday PM to bring us some rain.  Note how chilly (50s-60s) it is behind the front with 70s & 80s over the SE.  Chicago was 82 yesterday but they're in the 40s today with the winds off chilly Lake Michigan.   Burrr!
Until this upper low moves, I have little confidence in this weekend's forecast.  Stay tuned!

Well, from too much rain too little rain! I guess I should’ve warned you that I put fertilizer out, always the best way to predict no rain for a couple weeks. Thanks as always, I guess it’s time to fire up the irrigation
