NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
330 am CST Monday Dec 22 2014 


Discussion... 
when are we gonna see the sun? That has been one of our most asked 
questions lately...and I think it will be today. Southwest 
downslope flow has already eroded the low clouds as far east as 
Fort Worth and all areas should be partly to mostly sunny by middle 
afternoon...with only middle-high clouds to partially block the sun. 
Winds will veer westward and then northwest today as a cold front 
pushes into the area. 


Clouds will increase overnight as an upper trough follows the 
front. We are expecting a decent coverage of light rain...but 
precipitation will be light and quantitative precipitation forecast consequently low. Tuesday morning...a 
few models are hinting that it may get cold enough aloft to make a 
few flurries in western/northwestern counties. There is quite a 
bit of dry air below 5000 feet...and the middle layers are drying as 
well so the chance of any flurries seems low. Have not added them 
to the weather grids since if they occur they will not accumulate 
with temperatures above freezing...but they may provide visual 
interest in the aforementioned areas. 


Wednesday and Thursday mornings will be cool...with the northwest 
two thirds of north/central Texas possibly dropping to or just below 
32. Gusty south winds on Thursday plus sun and dry air will 
provide a rapid warm up and highs should be in the 60s. The dry 
air and gusty winds will elevate fire weather danger 
conditions...so outdoor burning should possibly be delayed for 
another day. 


The Friday cold front will produce highs below normal for 
Saturday...and near normal for Sunday/Monday. The European model (ecmwf) does bring 
a stronger trough across on Saturday...and if this feature 
continues in future runs...precipitation chances will increase. Of 
interest in the extended is a cutoff low in the southwest U.S. On 
day 10 that could bring multiple chances at precipitation next week. 84 


&& 


Aviation... 
/issued 1127 PM CST sun Dec 21 2014/ 
challenges include how long low MVFR ceilings persist on Monday 
morning...timing of wind shift and clearing after sunrise...then 
timing the arrival of a pre-frontal trough and cold front later in 
the day. 


The eastern two thirds of the metroplex continue under a canopy 
of MVFR stratus mostly below 2 kft and a broken cirrus canopy 
aloft associated with a shortwave disturbance. We will maintain 
the stratus canopy through middle morning Monday...before veering low 
level flow helps clear out the low levels with broken cirrus and 
VFR conditions. 


South winds 10-15 kts will become southwest by middle morning...then 
increase from the west around 15 kts by midday which may cause 
brief crosswind issues on north-south runways. The cold front 
will arrive by 21z with northwest winds 15-20 kts that are expected to 
decouple below 10 kts after nightfall Monday evening.
