NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
650 am CDT Friday may 22 2015 


Aviation... 
for the 12z tafs... varied flight conditions in place this morning 
/LIFR to VFR ceilings/ will improve to VFR by this afternoon as a 
warm front lifts north. Expect showers and thunderstorms 
to form along this feature but some uncertainty exists on 
coverage and where best heating will occur. Most likely areas for 
impacts appear to be west and southwest of the Interstate 45 
corridor this afternoon but confidence is not high enough to 
include more than vcsh/thunderstorms in the vicinity mentions at this time. As warm front lifts... 
expect easterly winds to become southeasterly and remain generally 
at or under 10 knots /with slightly higher winds at Galveston/. 
Ceilings expected to deteriorate to at least MVFR again overnight.

Previous discussion... /issued 501 am CDT Friday may 22 2015/ 


Short term... 
today through Saturday. 


Morning surface analysis shows yesterday/S cold front draped from 
the Texas coastal Bend eastward to the Florida Panhandle... with 
an expansive surface ridge sliding into the Southern Plains. The 
cold front is expected to lift north as warm front today as the 
surface ridge shifts over eastern Continental U.S.... with the front slowly 
climbing north throughout the day /reaching the Piney Woods region 
Saturday morning/. Expect shower and thunderstorm activity today 
to primarily be concentrated along this feature with coverage 
increasing with a bit with surface heating. Convective 
temperatures are generally around 80 degrees f this afternoon and 
the main inhibitor to reaching these temperatures will be clouds 
/courtesy moisture trapped underneath a frontal inversion/. Relative humidity 
forecasts do show some low level drier air working its way over the 
area around the surface ridge... and this should allow for enough 
breaks in the clouds to allow high temperatures to reach the low 
80s. Otherwise... carrying the highest probability of precipitation over the western and 
southwestern zones where front will lift farther inland. 


Rain will taper off overnight with loss of daytime heating but 
another round of showers and thunderstorms will be possible again 
on Saturday as smaller waves ahead of the upper low overspread the 
region on Saturday. With better instability in place Saturday 
afternoon /SBCAPE values 2500-3000 j/kg/ and forecast soundings 
showing an inverted-v signature... could see a strong storm or two 
north of the Highway 59 corridor but with 0-6 km bulk shear values 
around 20 to 25 knots storms will struggle to maintain 
organization. Main threat with any activity that develops does 
appear to be heavy rainfall with precipitable water values around 
1.8 to 1.9 inches. 


Huffman 


Marine... 


Unsettled weather will prevail across the bays and coastal waters 
through Memorial Day weekend with showers and thunderstorms over 
the coastal waters providing periods of heavy rain... increased 
rip current risk with elevated onshore flow... and Small Craft 
Advisory conditions expected over parts of the weekend and into 
the next week. 


A cold front located off the Upper Texas coast as of 3 am CDT 
will lift north today as a warm front with winds becoming easterly 
in its wake... resulting in some slightly above normal tides 
before veering to the southeast by Saturday afternoon and then 
south in response to an ejecting Lee surface low over the High 
Plains. Scattered showers and thunderstorms will be possible along 
this boundary today... with another round possible on Saturday. An 
increasing surface pressure gradient in response to the system 
over the High Plains will also result in elevated winds /20 to 25 
knots/ over the marine zones by Saturday evening... with seas 
building accordingly /reaching 7 to 8 feet/. This will create 
challenging conditions for small craft over the remainder of the 
Memorial Day weekend and mariners are advised to check current and 
forecast conditions before any Outing... as small craft advisories 
may be needed as early as Saturday evening. Additionally... 
increasing winds will also promote an increasing rip current risk 
along the Upper Texas coast. Thunderstorm chances will persist 
Sunday into Monday as a potent upper level system crosses the 
Great Plains... with a thunderstorm complex possibly crossing into 
the coastal waters late Sunday into early Monday. 


Deteriorated conditions are expected to persist through the remainder 
of the weekend... with some improvement possible in the Tuesday/Wednesday 
timeframe as wind speeds decrease as the gradient relaxes. 


Huffman 


Long term... 
Saturday night through Thursday. 


An active heavy rain period lies ahead. Saturday night a 4 
corners low will be drifting through Colorado as south-southwest flow aloft 
strengthens across southeast Texas. An impressive divergence signature sets 
up overhead with a short wave moving into the region. This should bring a 
round of heavy rain to the region. Low level jet strengthens for Sunday and 
fast training storms look likely across the area. Severe threat 
may also be on the increase for Sunday as well with impressive ll 
shear. Periods of heavy rain spread across the region Sunday night 
and Monday. The ingredients of unusually high precipitable water 
(1.9-2.1")/k-index values of 32-38/cape of 1800-3000j/kg during 
the daylight hours/srh 120-220 all present Saturday night through 
Tuesday. The potential for an extended period of heavy rain and 
flooding is on tap primarily from around 3 am Sunday beginning in 
the west then shifting and expanding east across the entire region 
Sunday by late in the morning and on through Monday night. A 
Flash Flood Watch will be needed as we get closer to the event and 
mainstem flooding also a threat with the wet ground and the 
already elevated river levels. Significant aviation impacts will 
be on tap from Texas up through Arkansas into MO and possibly even 
Chicago for this event. 


The rains and intensity should taper down late Tuesday as the 
upper trough lifts out and upper ridging tries to take hold across 
Mexico/TX. Rains may become more diurnal in nature on Wednesday 
needing the daytime heating and continuing through Thursday. For 
what it is Worth next weekend also looks wet but not with such a 
potent system. The European model (ecmwf) also trying to develop a tropical system 
in the east Pacific for at least 2 runs in a row.
