A FEW PRECIP ECHOES REMAIN OVER THE FAR SOUTH IN ASSOCIATION WITH THE COLD FRONT...BUT THESE SHOULD DISSIPATE AS THE BOUNDARY CONTINUES TO WEAKEN. A WEAK SHORTWAVE BEHIND THE MAIN SYSTEM IS ALLOWING SOME SHALLOW INSTABILITY TO REMAIN OVER THE NORTH...BUT THIS IS NOT PRODUCING MUCH MORE THAN SOME TOWERING CUMULUS. WITH WEAK UPPER RIDGING MOVING IN BY LATER THIS AFTERNOON...THE SUPPORT FOR THIS WILL DIMINISH. OTHERWISE...SUNSHINE AND A WARMING AIRMASS WILL ALLOW TEMPERATURES TO WARM TO AROUND SEASONAL NORMALS TODAY. THE BREAK IN THE ACTION LOOKS TO BE SHORT LIVED AS THE MODELS REMAIN IN GOOD AGREEMENT ABOUT THE NEXT WAVE...WHICH WILL MOVE THROUGH THE STATE TOMORROW.

WHILE THE FRONT MAKES IT THROUGH THE STATE BY EARLY SATURDAY MORNING...THE UPPER TROUGH IS EXPECTED TO HANG AROUND UNTIL SATURDAY AFTERNOON. THE COLD FRONT LOOKS SIMILARLY STRONG TO THE ONE YESTERDAY...AND IS EXPECTED TO DROP MAXES TO ABOUT 10F UNDER CLIMO WITH THE CLOUD COVER. HOWEVER...RAPID WARMING AND DRYING IS EXPECTED SUNDAY AS HIGH PRESSURE DEVELOPS OVER THE FORECAST AREA...ALLOWING MAXES TO WARM TO VALUES AT OR ABOVE CLIMO ONCE AGAIN. NO UPDATES EXPECTED TO THE FORECAST THIS MORNING. && .AVIATION...EST WINDS AT SLC TERMINAL THIS MORNING ARE EXPECTED TO TURN MORE NORTHERLY THROUGHOUT THE DAY.
