NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
1148 PM CDT sun Aug 2 2015 


Aviation... 
/06z tafs/ 


No concerns...VFR. 


Light winds...generally under 10kts...will prevail through the 
forecast period. When speeds fall to near 5kts...the direction 
typically varies...but the winds will be primarily from the 
southeast. 


Once again tonight...some high-based showers may enter western 
portions of North Texas...but these should only result in virga or 
sprinkles. No impacts are expected at any taf sites. Occasional 
middle/high clouds will pass through in west/northwest flow. 


25 


&& 


Update... 
no major changes required to the package this evening and the 
previous forecast remains in good shape. Increased cloud cover a 
tad and added a mention of sprinkles across most of our Red River 
counties Monday morning as a weak short wave trough may slide in from the 
north as forecast soundings show some middle/upper level moistening 
of the column. With the dry air still entrenched at the 
surface however...precipitation amounts should remain light. Cannot rule 
out a rumble of thunder or two with some instability being 
advertised by both the rap and NAM...but profiles are marginal for 
even isolated thunderstorms. 


Updated zones and other associated products have been sent.

Previous discussion... /issued 334 PM CDT sun Aug 2 2015/ 
an axis of middle level moisture persists across northwest Texas 
and we are expecting isolated showers to develop again just 
northwest of the County Warning Area overnight. It is possible a few of these 
showers may move into far northwest portions of the County Warning Area and we will show 
a mention of such activity in the forecast through Monday morning. 
The low levels remain very dry...and thus very little if any 
measurable rain is expected. For the remainder of the area 
another tranquil night is forecast. Dewpoints will be in the 50s 
this evening which should make for somewhat pleasant conditions 
for early August. Surface moisture will be on the increase later 
tonight and into Monday as winds become more southerly in the 
lower levels. So unfortunately the humidity will be returning to 
more normal levels during the next couple of days. 


An upper level high will intensify over Arizona and New Mexico 
this week...but north central Texas will remain on its eastern 
fringe. This means upper level subsidence will not be too 
prominent...and once low level moisture recovers enough the 
airmass will actually be unstable during the afternoon hours with 
little to no cin. With northwest flow aloft prevailing over the 
County Warning Area through the week...it is certainly a pattern that could make 
the weather go from dry to - surprise it is raining. At this 
point the ingredients required to produce convection do not appear 
to come in phase with one another...but again this is not a 
pattern where dry weather is a certainty. 


On Monday night a strong shortwave trough will kick off storms in 
the High Plains. Favorable steering flow aloft exists for a mesoscale convective system to 
form and track into the area...but low level moisture/instability 
just look too limited for any complex to make it this far south 
and affect the area Tuesday morning. Moisture and instability 
increase dramatically by Wednesday afternoon...but by this time 
there is a lack of forcing as the primary shortwave trough moves 
east into the Mississippi River valley. Have inserted a slight 
chance of afternoon/evening storms in the forecast Wednesday over 
the northeast zones where the tail end of the forcing may interact 
with the unstable/uncapped airmass. Otherwise have shown probability of precipitation of 
10 percent Tuesday and Thursday north of I-20 but kept the worded 
forecast dry. The rain chances increase a little by Friday evening 
and into Saturday when a weak cold front should drop into the Red 
River valley and stall. Will show just slight chances of showers 
and storms over the northern and northeastern zones. 


Again the majority of the region next week should contend with 
just hot and dry weather. Temperatures will gradually inch up into 
the 98 to 103 degree range over the entire area by late in the 
work week. It appears that heat advisory criteria may occur over 
portions of the County Warning Area by middle-late week. By next Sunday...the upper 
high should become centered over Texas which will promote hot and 
dry weather well into middle August.
