/ISSUED 357 AM CST FRI MAR 11 2016/ Upper low has begun to slowly lift north into South TX and will be responsible for precip chances today through Saturday. The idea of widespread precip w/ generally light precip amounts is consistent with an upper low tracking over the region though not any one time frame should be considered a wash out. The aforementioned upper low will be weakening as it lifts north of the region by Sat night. with attention then turning to a compact wave ejecting ahead of the larger wave trough currently approaching the West Coast.
Low pressure area with areas of heavy rainfall across the lower Mississippi River Valley currently will remain to our west through this period. Our area will remain between that low pressure area and high pressure across the western Atlantic Ocean. deep upper low is slowly wobbling across deep south Texas with a strong upper ridge situated off the Florida east coast. This is reasonable with the higher moisture axis to our west and the drier low/mid level air on the 00z TAE sounding.

THIS FRONT WILL MERGE INTO THE SHARP PIEDMONT TROF TUESDAY EVENING. PERHAPS A COUPLE OF DEGREES COOLER ACROSS THE NORTH IF THE SOUTHERLY SURGE OF COOLER AIR PROGRESSES A LITTLE QUICKER.
A LOW PRESSURE TROUGH WILL DEVELOP ALONG THE WEST COAST THIS WEEK CONTINUING THE DRYING TREND. ALONG WITH COOLER WEATHER.
ON THE NORTH SIDE OF THIS BOUNDARY SLIGHTLY COOLER AND DRIER AIR HAS PUSHED SOUTH ACROSS MUCH OF THE FORECAST AREA. WHERE THE MONSOONAL MOISTURE IS THE HIGHEST. MODELS SIMILAR IN PUSHING THE SYNOPTIC FRONT BACK TO THE NORTH AS A WARM FRONT FOR THE DAYTIME HOURS ON WED. WHICH WILL LEAD TO A CHANCE OF SHOWERS AND THUNDERSTORMS FOR MOST LOCATIONS AS THIS WARM FRONT PUSHES NORTH INTO NORTHERN KS. AS THE TROPICAL RIDGE BEGINS TO BUILD BACK ACROSS THE PLAINS. THIS WILL LEAD TO WARMER TEMPS FOR THU AND ESPECIALLY FOR FRI AND SAT. AS THIS WARMER AIR BUILDS BACK IN.
Instability ahead of an upper trough off the California coast is being drawn up into west Texas providing greater areal coverage than yesterday.
WESTERLY WINDS WILL INCREASE AFTER 15Z AS A LOW LEVEL TROF SHIFTS SOUTHWARD INTO NORTH ALABAMA. THIS TROF WILL TRIGGER SCT TSTMS ACROSS NORTH ALABAMA TUESDAY AFTERNOON AND EVENING.
