.SHORT TERM...(TODAY THROUGH TONIGHT )
ISSUED AT 348 AM MDT FRI MAR 27 2015

NORTHWEST FLOW ALOFT CONTINUE OVER COLORADO WITH A RIBBON OF
MOISTURE AND EMBEDDED WEAK DISTURBANCES DROPPING SOUTH ACROSS THE
PLAINS. THE WHOLE PATTERN IS SHIFTING SLOWLY EAST...LEADING TO
WARMER TEMPERATURES AND DRYING OVER THE WESTERN PART OF OUR AREA.
THERE IS A LITTLE GAP IN THE DEEPER CLOUDS AND SHOWERS OVER
EASTERN WYOMING AT THIS TIME...SO THE CURRENT SHOWER ACTIVITY NEAR
THE EASTERN BORDER SHOULD BE DECREASING BY SUNRISE. HOWEVER THERE
IS ANOTHER LITTLE RIPPLE UP IN MONTANA THAT WILL LIKELY LEAD THE
WESTERN EDGE OF THE MOISTURE BAND TO FILL IN AGAIN BY AFTERNOON. WILL
HANG ONTO LOW POPS FOR THE NORTHEAST CORNER AND KEEP QUITE A BIT
OF CLOUDS OVER THE PLAINS THROUGH THIS EVENING. FOR THE MOUNTAINS
THERE WILL BE A BATTLE BETWEEN THE DRYING AND THE REDEVELOPMENT OF
SHALLOW CONVECTION...EXPECT THERE WILL BE SOME INCREASE IN CLOUD
COVER THIS AFTERNOON THOUGH ANY SHOWER ACTIVITY SHOULD BE VERY
LIMITED IF THERE EVEN IS ANY. TEMPERATURE FORECAST LOOKS ON TRACK
WITH ABOUT 10 DEGREES OF WARMING OVER YESTERDAY.
