Under Pressure

High atmospheric pressure that is!  Once the arctic front passed through this morning with a temperature drop that would make the Plains' states proud, high pressure will be building to the south and east over the next several days.  Take a look at the NWS WFC prog for tomorrow...

For this time of the year, that is one gnarly HIGH!  High pressure, that is where the air presses harder down towards the earth, is characterized by dry and cold air, thus making the air mass heavier and more dense.  And note the 24 hour temp change!

And it's no wonder the northern plains are rebounding as their max temps weren't so much....

It will take the remainder of this work week for the air mass to moderate back towards normal temps.  In fact, for those of you with weekend plans, the high pressure should hold out long enough and fend off any overrunning SW advection that might cause clouds and light precip by Monday?  The Euro seems to think that Sunday will be relatively mild and nice for this time of year.  Here is its prog for the 850 mb temps Sunday morn...

But...another arctic front is on the way!  Here is the Euro's depiction of one mile up for next Wednesday am!  Some of the ensemble members actually have a wave of low pressure on this boundary from deep in the heart of Texas and it marches precip along the boundary towards the Mid-Atlantic.  That solution is seen on all of the global modeling, but none of the actual operational models have anything to get excited about.

HPC plays it by the vest as they have another huge arctic high taking wx control; albeit earlier than the Euro.  We have assumed control...we have assumed control...

And by next Thursday, HIGH PRESSURE will once again rule the roost...at least the GFS thinks so...

OK...I made a reference to a song I heard this past summer that I still can't get out of my head!  It is a pretty awesome 5th inning mid-game song...maybe as good as The O's "Thank God I'm a Country Boy" in their 7th inning stretch.  But seeing east TX has only whetted my appetite to visit west TX now...I hope you enjoy this as much as I...and don't feel "pressured" to agree with my tastes!

Enjoy your mid-week...and your 10°-15°F below normal Wednesday...and that doesn't include the wind!

AA:  High pressure to control our wx through the weekend.  Then another frontal passage for yet another arctic high for later next week!  By the way, not an American League guy as you know, but I had a blast at Texas Rangers game!
