NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
556 am CDT Sat Apr 19 2014 


Aviation... 
light winds will pick up out of the south at 8 to 10 kts around 
15z /10 am/. Conditions should remain VFR at all locations today 
and tonight...with the only cloud cover being in the form of 
cirrus. Some stratus may surge north Sunday morning...and we have 
gone ahead and included a line for the extended dfw taf to include 
a cloud deck at 2500 feet at 7 am /13z Sunday/. Rain chances prior 
to 18z Sunday still appear too low to include in the dfw extended 
taf. Better chances of precipitation are expected after 20/18z as 
a southern branch shortwave moves east across the Southern Plains.

Previous discussion... /issued 312 am CDT Sat Apr 19 2014/ 
water vapor satellite imagery shows a shortwave moving into far 
West Texas near El Paso at 0730z /230 am CDT/. Lightning was 
detected over West Texas south of Carlsbad New Mexico. The 
shortwave will move northeast across West Texas today bringing a 
chance of showers and thunderstorms to West Texas today. 


The main shortwave was located over the northern part of Baja California 
California. This shortwave will lift northeast across across New 
Mexico Sunday and then slowly east across Oklahoma Sunday night 
through Monday. We will see a chance of showers and thunderstorms 
starting after midnight Saturday night across the western third of 
North Texas...and chances will spread east during the day Sunday 
across the rest of north and central Texas. A few strong to 
severe storms cannot be ruled out Sunday afternoon...especially 
across the northwestern third of the forecast area. Rain chances 
will continue Monday as the upper level system slowly moves east 
across Oklahoma. Strong lapse rates and moderate deep layer shear 
should be conducive for some severe thunderstorms across north and 
central Texas Monday afternoon. Large hail and damaging winds will 
be possible with some of the thunderstorms. 


A cold front will enter the northwestern zones Monday afternoon 
and move through the southeastern zones before daybreak Tuesday. 
Rain chances will end from northwest to southeast Monday night. 
Middle level ridging will build in Tuesday behind the exiting upper 
level trough. This will result in dry weather and a warming trend. 


A strong upper level system will move into the northern plains 
Thursday with a trough extending southwest into New Mexico. We 
will see a slight chance of showers and thunderstorms across the 
northwestern zones before daybreak Thursday and chances will 
spread east during the day Thursday. Rain chances will end from 
west to east Thursday night.
