Much Warmer Over The Central & Eastern US This Week

 

The latest Monday morning water vapor satellite image shows the weather features that will influence the nation’s weather this week nicely.  It will be much milder over the central and eastern US compared to last week when a slow moving Spring storm led to cool and stormy conditions.  High pressure will build strongly into the central US today and Tuesday, allowing temperatures to jump into the 80s and 90s, especially over central Texas where highs will flirt with the triple digits while driving some demand for cooling.  The high will expand toward the Midwest and eastern US throughout the week, which will also bring much appreciated warmth to these regions as temperatures warm into the 70s and 80s.  Until then there will be a few weak weather system grazing across the far northern US for a few light showers today while maintaining cool conditions as highs struggle to get out of the 50s.   The reason for the big warm up this week is because of a cold trough of low pressure moving into the western US.  This will allow the warm high pressure ridge over the southern Plains to expand and shift east, which it hasn’t been able to do much at all this winter season.  However, the pleasant weather won’t last long as the trough coming out of the West will bring another period of stormy weather to much of the US during the middle of the week while reinforcing cool blasts return this weekend and last through the middle of May.

 

1)  Strong high pressure over Texas and the southern Plains will expand across the central and eastern US over the coming days as temperatures warm above normal.  The high pressure ridge shows up nicely with the norther peripheral boundary of it being where dark brown colors (dry) transition to the milky white (more moisture).

 

2)  A deep cold trough over the West will be the reason for kicking the Plains high pressure ridge east.  It will bring valley rains and mountain snows to portions of the western US before bringing heavy showers and thunderstorms to the central US during the middle of the week.

 

3) A weak weather system will ride along a stalled frontal boundary and lead to scattered showers over the Great Lakes and into the Ohio Valley.  This will also keep conditions relatively cool over the next few days before a nice late week warming trend takes place.

 

4)  Cool conditions over New England will hold on a few more days due to this past weekends cool blast that will take time to scour out and modify, which will happen as the week progresses.

Wednesday will be quite warm over much of the central and eastern US as high pressure builds in.  This will bring temperatures of 70s and 80s with 90s into the Plains.  The western US will be cool as a weather system tracks through and approaches the Midwest late in the week.
