Weather Discussion 4: 5-19-2008
DISCUSSION...SOME LIGHT PATCHY FOG WILL DISSIPATE AS THE DAY CONTINUES. A SMALL AREA OF HIGH PRESSURE WILL IMPACT TODAY'S WEATHER LEAVING THE AREA WITH CLEAR SKIES FOR MOST OF THE DAY. ALTHOUGH THE COLD FRONT MADE ITS WAY THROUGH THE VALLEY OVERNIGHT, A STATIONARY/ WARM FRONT IS BEGINNING TO TAKE SHAPE OVER THE ALABAMA/ TENNESSEE BORDER WHICH COULD BRING INCREASING CLOUDS FOR LATER IN THE DAY.
SHORT TERM...CLEAR SKIES FOR MOST OF MONDAY. WARM FRONT MAKES ITS WAY NORTH INTO THE EVENING HOURS, INCREASING THE CLOUD COVERAGE. ALONG WITH THE CLOUDS COMES IN CHANCE FOR A FEW SCATTERED SHOWERS FOR MONDAY NIGHT. THE WARM AIR ADVECTION ASSOCIATED WITH THE WARM FRONT ALONG WITH A SHORTWAVE SYSTEM FROM THE WEST COULD COMBINE TO GIVE THE CHANCE FOR A FEW SCATTERED THUNDERSTORM CHANCES FOR TUESDAY MORNING.
LONG TERM...RAIN CHANCES DECREASE THROUGH THE DAY TUESDAY, TAKING WITH IT THE CHANCE FOR THUNDERSTORMS. A WEAK LOW PRESSURE SYSTEM SITUATED OVER THE NORTHERN PLAINS WILL MAKE ITS WAY ACROSS THE REGION, BRINGING A SLIGHT CHANCE FOR RAIN COME WEDNESDAY. A LOW PRESSURE OVER THE NORTHEAST AND THE FORMATION OF A LOW OVER THE SOUTHWEST WILL DEVELOP A RIDGE OF HIGH PRESSURE OVER THE PLAINS, BRINGING WARMER TEMPERATURES INTO THE 80'S FOR THE TENNESSEE VALLEY REGION COME THURSDAY INTO FRIDAY.
