NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
619 am CDT Tuesday Oct 21 2014 


Aviation... 
an upper ridge will shift east of North Texas during the next 24 
hours while an upper trough slowly approaches from the west. 
Increasing high clouds are expected as the trough draws 
nearer...otherwise overall weather conditions should remain 
fairly quiet. 


At the surface...a high pressure ridge centered just east of the 
region will provide weak southeasterly low level flow. Surface winds 
have become calm at most locations...which when combined with clear 
skies and dewpoints in the upper 50s has led to some patchy fog. 
Dewpoint depressions remain sufficient in the metroplex to 
preclude fog development...and we will continue to leave out the 
mention of fog at Dallas-Fort Worth area terminals. The exception 
will be gky where a tempo for 5sm should suffice. Otherwise kact 
will likely experience MVFR visibilities until 15z. Increasing 
clouds tonight should limit additional fog development in the 
extended portion of the tafs.

Previous discussion... /issued 315 am CDT Tuesday Oct 21 2014/ 
another unseasonably warm day is in store for North Texas as upper 
level high pressure remains the over the region. Although the best 
Gulf moisture will continue to ride up the Rio Grande Valley...the 
combination of shallow moisture...a light wind and a mostly clear 
sky will result in some patchy fog across most of North Texas this 
morning. The fog could be dense in a few locations for a short 
time. However...the visibility at most locations should remain 
above 1 mile so we will not issue a dense fog advisory at this 
time. We will monitor visibility trends closely through sunrise. 


The upper level ridge axis will translate slowly east tonight 
through Wednesday as a short wave trough approaches from the 
Desert Southwest. Weak large scale forcing and elevated moisture 
will bring a slight chance of showers and isolated 
thunder...mainly north of the Interstate 20 corridor Wednesday 
night and Thursday. Since deep moisture and lift will be 
lacking...we will keep probability of precipitation at 20 percent. The passage of the 
upper trough will bring increased cloud cover which should keep 
temperatures a few degrees cooler on Thursday. 


The upper trough axis will move quickly east of the region 
Thursday evening as a ridge of high pressure builds in from the 
west. The upper ridge will amplify as it translates east through 
early next week. Building heights and a mostly clear sky will 
result in unseasonably warm temperatures Friday through Sunday 
with highs in the 80s and lows mainly in the 60s. 


The upper ridge will build toward the East Coast Sunday night and 
Monday while a progressive trough approaches from the west. The 
trough should move through North Texas dry Monday night but once 
it passes to the east it will allow a cold front to enter the 
region. The arrival of the front may bring just enough moisture 
and lift to produce a few showers and thunderstorms on Tuesday of 
next week.
