It will be interesting to see what accumulations we get in the alpine. forecast.weather.gov/MapClick.php?CityName=Silverton&state=CO&site=GJT&lat=37.82&lon=-107.64#.Uj9HU4asiSp " IF THERE WAS A "PERFECT STORM" SCENARIO OUTSIDE OF WINTER...TODAYS SCENARIO IS IT. A POWERFUL SHORT WAVE EJECTING ACROSS SRN NEVADA WITH IMPRESSIVE DIFFERENTIAL CYCLONIC VORTICITY ADVECTION REACHES THE FOUR CORNERS REGION THIS AFTERNOON...DEVELOPING A MID LEVEL CLOSED LOW CIRCULATION WITH STRONG DIVERGENCE COVERING WRN COLORADO. MONSOONAL MOISTURE STREAMS NORTHWARD AHEAD OF THE SHORT WAVE WITH PWATS APPROACHING NEARLY AN INCH OVER SERN UTAH AND THE GRAND VALLEY. BULK SHEAR VALUES (0-6 KM AGL LAYER) FROM THE RAP13 APPROACH 50-70 KTS ACROSS THE SRN PORTION...COMBINED WITH INCREASING DYNAMICAL LIFT...SUPPORT ROTATING UPDRAFTS THAT SHOULD PRODUCE LARGE HAIL AND DAMAGING WINDS FROM SQUALL LINES.
