629 AM MDT TUE APR 19 2011

.DISCUSSION...THE PREVIOUSLY MENTIONED COLD FRONT IS NOW SOUTH
OF THE BURN SITE THIS MORNING. THE NORTHWEST PRESSURE GRADIENT IN
PLACE IS EXPECTED TO RAMP WINDS UP LATE THIS MORNING THROUGH THE
AFTERNOON ALLOWING FOR EXCELLENT MIXING AND UNLIMITED CI VALUES.
HAVE BACKED OFF OF PRECIP FOR TODAY AS BULK OF CONVECTIVELY
DRIVEN SHOWERS LOOK TO REMAIN TO THE NORTH ALONG THE WASATCH
PLATEAU...BUT EXPECT SOME MIDLEVEL CLOUD BUILDUPS TO FORM DURING
THE HEATING OF THE DAY. WINDS WILL BEGIN TO BACK AROUND TO
SOUTHWESTERLY FLOW ALOFT TONIGHT ALLOWING A MORE TYPICAL
DIURNALLY DRIVEN DOWNSLOPE TO DEVELOP...WITH SPEEDS GRADUALLY
RAMPING UP WEDNESDAY AS MIXING INCREASES MIDDAY. A SLIGHT CHANCE
OF SHOWERS EXISTS FOR LATE WEDNESDAY AFTERNOON...BUT AGAIN PRECIP
SHOULD DEVELOP MAINLY TO THE NORTH. NOT LOOKING AT SIGNIFICANT
PRECIP UNTIL THURSDAY...MOST LIKELY IN THE AFTERNOON AS THE NEXT
COLD FRONT SAGS IN FROM THE NORTH.
