AGAIN ANOTHER MILD NIGHT ACROSS THER REGION SETS THE STAGE FOR GOOD MIXING AND AS THE HIGHER WINDS ASSOCIATED WITH THE JET STREAK SHIFT ACROSS THE AREA THIS WILL BRING GUSTY WINDS BUT WINDS ALOFT ARE NOT AS STRONG AS THE PREVIOUS COUPLE OF DAYS. COOLER START BUT SUNNIER SKIES AND DOWNSLOPE FLOW WILL BRING A DRY SUNDAY WITH TEMPERATURES REBOUNDING WELL INTO THE 40S. WILL BE SOME OF THE LIGHTER WINDS WE HAVE SEEN IN RECENT DAYS SO DESPITE THE COOLER TEMPERATURES SHOULD BE PLEASANT FOR OUTDOOR ACTIVITIES. A PUSH OF PACIFIC MOISTURE ALONG A WEAK WARM FRONT MOVING THROUGH SUNDAY NIGHT COULD BRING A BIT MORE SHOWER ACTIVITY BUT NOT MUCH MOISTURE IS EXPECTED.

350 AM CST SAT FEB 20 2016 IT APPEARS WE ARE TRANSITIONING INTO A COOLER AND WETTER PATTERN.
935 PM PST FRI FEB 19 2016 An upper level low will move through the region tonight and Saturday and will result in moderate to heavy mountains snow, valley rain, and very gusty winds. High pressure this weekend will bring a return to mild weather and less wind. Otherwise the showers brought about by this cold front passage and the conditionally unstable airmass they are being produce from should keep showers going for a bit longer where the winter weather highlights remain in effect for tonight. /Pelatti 06Z TAFS: Cold front moved through the aviation area and brought precipitaiton in the form of rain with generally mountain snow showers and gusty wind.

IN SOUTHERN MIDDLE TN COUNTIES HIGHS IN THE LOWER TO MID 60S ARE EXPECTED. ANOTHER COLD FRONTAL BOUNDARY IS POISED TO MOVE SOUTHWARD ACROSS THE AREA TONIGHT.
THIS BOUNDARY WILL CONTINUE TO PUSH SOUTHWARD TOWARDS THE I-40 CORRIDOR AS THE EASTERN H500 TROUGH CONTINUES TO CHURN ALONG THE OHIO RIVER VALLEY TOWARDS THE GREAT SMOKY MOUNTAINS.
