...DISCUSSION...
AN AMPLIFIED UPPER-LEVEL PATTERN IS EXPECTED THROUGH MUCH OF THE
WEEK...ALTHOUGH SOME GUIDANCE VARIABILITY EXISTS WITH LATE-WEEK
DETAILS REGARDING THE EASTWARD PROGRESSION OF AN UPPER TROUGH OVER
THE WESTERN STATES. SURFACE HIGH PRESSURE/DRY CONDITIONS WILL
GENERALLY BE PREVALENT OVER THE EASTERN HALF OF THE CONUS MUCH OF
THE WEEK...WITH MODEST MOISTURE AND A LACK OF STRONGER
FORCING/VERTICAL SHEAR EXPECTED TO PRECLUDE MEANINGFUL SEVERE RISKS.
THAT SAID...SOME STRONG STORMS MAY BE POSSIBLE AROUND DAYS 5-7
FRIDAY-SUNDAY ACROSS PARTS OF THE EASTERN GREAT BASIN/CENTRAL
ROCKIES VICINITY AS THE WESTERN STATES UPPER TROUGH/COLD FRONT SHIFT
EASTWARD...WITH SOME SEVERE POTENTIAL POSSIBLY REACHING THE HIGH
PLAINS LATE THIS WEEKEND/EARLY NEXT WEEK.
