    Patchy dense fog and drizzle are expected to occur mainly along and west of Interstate 35 through mid morning. Localized visibilities may fall to below a mile across low-lying areas and any drizzle may make roads wet and slick in spots. When commuting early this morning... remember to allow extra time for travel...slow down and use low beams if you encounter patchy dense fog.

NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Fort Worth Texas 
656 am CDT Tuesday may 26 2015 


Aviation... 
/12z tafs/ 


Concerns...IFR ceilings/visibility early...PM thunderstorm potential. 


A rain-cooled nocturnal boundary layer easily saturated during the 
predawn hours. On the western periphery of an exiting cloud 
shield...enhanced radiational cooling resulted in some patchy fog. 
But as a 30-40kt low level jet lifted over the shallow surface layer...IFR 
ceilings also developed. The ceilings arrested the cooling...and 
as southerly surface winds gently warmed the surface...relative humidity values 
fell below 100 percent...and visibilities steadily improved. 
However...the supersaturation will continue within the cloud 
deck...and patchy drizzle will linger until the late may sun warms 
the surface layer. This insolation will lift IFR ceilings into the 
MVFR category by mid-morning. VFR conditions will prevail this 
afternoon...but a warm layer at 850mb may maintain VFR ceilings. 


A dryline will invade western North Texas this afternoon. 
Thunderstorms are expected to develop along the boundary and move 
eastward into the I-35 corridor during the late afternoon or early 
evening hours. With tremendous instability...this activity will 
maintain its intensity after dark...and may pose a severe weather 
threat to taf sites. The activity will eventually weaken in 
intensity as it moves east of the I-35 corridor late this 
evening.

&& 


Previous discussion... /issued 346 am CDT Tuesday may 26 2015/ 
an unsettled weather pattern will continue through the remainder 
of the week and into the weekend...as large-scale troughing aloft 
continues across the western Continental U.S.. the complex of severe storms 
that affected the area yesterday afternoon and evening has now 
moved away from the area and into the Upper Texas coast and lower 
Mississippi Valley early this morning. In the wake of this large 
scale mesoscale convective system...clearing was occurring across western North Texas. 
Wherever southerly wind speeds drop off across this area...patchy 
dense fog will continue to form due to saturated soil and 
radiational cooling taking place. We will have the patchy dense 
fog advertised for areas along and west of I-35/35w with the 
clearing line reaching this corridor by sunrise. The feeling is 
currently a dense fog advisory will not be needed as most areas 
should continue to see south winds near 10 miles per hour this morning. 


The next shortwave disturbance currently moving over New Mexico 
will arrive during prime heating today. A surface dryline 
currently near the nm/Texas border will move east with the shortwave 
disturbance today. Very high instability values in excess of 4000 
j/kg SBCAPE and middle level lapse rates in excess of 7 degree/c are 
expected out ahead of the surface dryline with deep-layer westerly 
bulk shear values approaching 40-45 kts. High resolution models 
all agree on at least initiating isolated to scattered storms on 
the dryline by middle-late afternoon. Subsidence from this morning/S 
linear mesoscale convective system should have shunted east by this time with discrete 
supercell thunderstorms expected at least into the early evening 
hours with greatest coverage expected to be north of I-20 and west 
of I-35/35w. This activity should move east-southeast later 
tonight with the mean steering flow into counties downstream. 
Storm coverage will likely diminish overnight tonight as 
convection moves into an area of weaker low level southerly flow 
and the shortwave responsible for the lift moves east out of the 
area. All modes of severe weather will be possible...including 
tornadoes through middle evening. Afterward...we expect damaging 
winds...hail...and localized heavy rainfall to be the main 
threats. We will not re-issue a new Flash Flood Watch at this 
time...as the small-scale mesoscale system should move 
progressively enough to keep widespread flooding from occurring. 


A brief lull in convective activity is expected Wednesday into 
much of Wednesday evening...as small-scale ridging aloft and 
associated subsidence take hold. An isolated thunderstorm cannot 
be ruled out through heating of the moist airmass...however 
sustained strong to severe convection is not expected. Weak 
shortwave energy over Oklahoma will produce late day storms north 
of the Red River valley Wednesday evening. A couple of high res 
models want to produce enough of a cold pool to move any storms 
into our far northwest counties before daybreak Thursday morning. 
Confidence is not high and many mesoscale factors are uncertain. 
Nevertheless...we will advertise slightly higher probability of precipitation up across 
the northwest Wednesday night. 


By Thursday...another sharp shortwave disturbance will rotate 
east within the base of the larger scale western Continental U.S. Trough 
across the 4 corners and toward the Southern Plains later Thursday 
into Friday in a negative-tilted fashion. The bulk of the 
strongest lift will be north of I-20 and northward into the 
Central Plains. As such...will have highest rain chances across 
the north and lesser to the south. The environmental set up for 
the late week activity remains uncertain for the potential for 
severe weather...however there is higher confidence that pockets 
of heavy rain could occur to the northern half of the County Warning Area where 
ongoing river flooding and saturated soils continues to exist. 
Future watches for flash flooding look probable and we will re- 
evaluate the need as the week progresses. Temperatures will 
continue to remain near or below seasonal normals depending on 
coverage of showers and thunderstorms. 


The large-scale western Continental U.S. Upper trough does appear to begin 
shifting eastward across the plains over the weekend with a cold 
front arriving late in the weekend. Low rain chances will be held 
during this period before large-scale upper ridging appears to 
finally shut the spigot off early next week/the first week of 
June. We can only hope this is the case after weeks of severe 
weather...heavy rains...flash flooding and river flooding.
