 Public Information Statement  Statement as of 10:15 am CST on March 4, 2015


... All clear message for the tornado drill...

This message serves as the all clear for the test Tornado Warning
that was issued at 10 am. This tornado drill was part of severe
weather awareness week when we review preparedness information
related to severe thunderstorm hazards. The tornado drill is
conducted every year and is a good opportunity for
schools... businesses and families to practice what they would do
in the event of an actual Tornado Warning.

It is important for all to have a way to get weather warnings...
to have a plan what to do in the event of a warning including
where to shelter... and to practice that plan from time to
time... whether you are at home... school or work. For more
information on severe weather awareness week and tornado safety go

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1027 am CST Wednesday Mar 4 2015 


Marine... 


Sea fog still ongoing and should continue until the front scours out 
the moisture. Some breaks this afternoon look likely improving to 2 
to 5 miles at least for a few hours...then fog returns tonight. 
Dense fog advisory extended until around midnight. Very strong cold 
front will bring gales to the Upper Texas coast beginning around 
midnight. Low water advisory for strong north winds. Very strong 
currents expected in the wake of the frontal passage and especially 
Thursday morning for the low tide. Sustained northerly winds 25 to 
35 knots with gusts 40-50 knots. 


45 
&& 


Aviation... 


Ceilings improving and expect MVFR ceilings should improve to VFR by 18-20z 
across most sites...Galveston may not get there as dense fog threat 
returns with visby 1/4 to 1/2 mile late this afternoon. A few 
showers will be possible today and if we get enough breaks may get 
isolated thunderstorms but coverage if any should be minimal and 
won't include any thunderstorms and rain in package. Frontal timing still around 22z 
cll-01z iah-06z gls. Very strong and gusty northerly winds in the 
wake of the frontal passage. 00z and the 12z (nam) models keeping a warm nose 
over most of the sites which should preclude any wintry mix of 
precipitation...the possible exception being cll which might see some sleet 
with above freezing temperatures at the surface. 
45

Previous discussion... /issued 1008 am CST Wednesday Mar 4 2015/ 


Update... 
current forecast is in good shape this morning. Strong onshore 
flow ahead of an approaching cold front will allow temperatures to 
climb into the upper 70s today. The front has pushed into North 
Texas where temperatures are quickly falling into the low 40s. 
The front should arrive in our northern counties around 4pm and 
into the metropolitan area after 7pm with strong north winds and falling 
temperatures in its wake. 38 


Previous discussion... /issued 705 am CST Wednesday Mar 4 2015/ 


Discussion... 
yesterday's warm front is north of the County Warning Area with any interior dense 
fog forming along its northern periphery. A very warm and moist 
environment out there this morning with average regional temperatures 
and dew points in the upper 60s. These very warm and more humid 
Wednesday conditions will ultimately play a critical role in the 
Post-frontal of what will likely not be much up north concerning 
the lack of any sig impacts from a possible rain/sleet wintry mix. 
Low probability of precipitation today for only drizzle/mist or very light short-lived showers. 
A 40 knots low level jet (35 knots just-off-the-surface winds on khgx's VAD wind 
profile) has inhibited inland fog formation. Different story over 
the waters as high near 70 f dew point air over cool shelf waters in 
the lower 50s has kept areas of dense fog in place...this type of 
fog will remain through late morning with afternoon improvement to 
just areas of 3 to 5 mile fog. As winds begin to weaken just 
downstream of an approaching central Texas cold front...coastal 
area/maritime fog may thicken up after tonight's sunset. Thinning 
afternoon cloud cover...due to moderate onshore mixing winds and the 
remnants of the ever-weakening low level jet... will have afternoon 
temperatures again warming into the middle 70s up north to around 80 
f over the southern third of the County Warning Area. Enjoy this last day of 
'spring'. 


The much advertised cold front will enter our far northwest forecast area around 
sunset...this boundary to swing light vrb breezes around to north-northwest 
in the city around 9 PM...strong northerlies at the coast from 
midnight Onward. Western and coastal County wind advisories will 
be likely tonight into Thursday morning for greater than 25 miles per hour 
winds. The following air mass is frigid/dry...current Central Plains 
temperatures of low teens/single digit dew points...translates to 
strong cold air advection. From tee shirts to Coats within a day as 
there will be around a 35 to 40 degree 24 hour temperature 
differential. The column will certainly cool to near freezing across 
the north...but timing may be delayed. This delay may place the 
coldest temperatures over diminishing precipitation. Cooling does 
occur during the Thursday morning Post-frontal period of more of an 
overrunning precipitation event...the far northern County profile 
has a near 2,500 foot below freezing lower 900 mb layer. As 
mentioned earlier...the ground and surrounding (elevated) 
roadways/bridges will likely be too warm so have excluded any 
mention of -fzra. With the precedent warm conditions...along with a 
profile that supports a rain/sleet mix...any accumulations leading 
to any significant travel impacts is very low at this point in time. 
The latest nwp model runs have northern County Thursday 12z surface 
temperatures in the middle to upper 30s (raw/mos). Higher rez WRF is 
split on the onset of freezing surface temperatures with the arw/nmm cores a 
touch faster than the NCEP solution. Bottom line is that the 
majority of solutions are coming in with above freezing 2m 
temperatures during the highest chance for precipitation....a 
rain/sleet event with little to minor impacts. There may be some 
rumbles of thunder late Wednesday/early Thursday as middle-level 
cooling and lift from the boundary itself (within a great 1.5 inch precipitable water 
air mass) may provide just enough ll instability to generate 
isolated lightning. 


All inland precipitation comes to an end by Friday morning...weakening 
northerlies under clearing skies will allow thermometers to 
plummet into an areawide freeze. The freezing line will likely 
reach the coastal counties...average upper 20s north of the city 
to around freezing elsewhere/middle 30s at immediate coast. May want 
to make the preparations now to protect your 3 p's for a minor 
freeze (people pets and plants). A developing southwestern 
Continental U.S./Northern Mexico 500 mb trough set-up through the upcoming 
weekend into early week. A series of weak disturbance passing up 
ahead of this broad trough will increase probability of precipitation (for mainly showers) 
to high chances Sunday into early Monday. Solutions diverge from 
day 7 on with the more wet GFS developing a western Gulf surface 
trough...the less aggressive Euro placing higher quantitative precipitation forecast further south 
and offshore. Temperatures will subsequently warm back into the 
60s by early week...mornings remain in the chilly 40s. 31 


Marine... 
although there could be intermittent improvements in visibilities at 
times...the threat of sea fog will persist into the evening hours. A 
strong cold front is expected to move off the coast late this 
evening...probably right around midnight (slightly before that in 
the bays). Strong north winds are expected behind the front...with 
frequent gusts to gale force likely into Thursday afternoon. Next 
shift will likely need to upgrade the gale watch to a warning once 
timing is further nailed down. Strong offshore flow will also 
transport some water out of the bays so will need to monitor 
potential for low water advisory on Thursday. Wind speeds will very 
slowly diminish beginning Thursday night and become northeast into 
the weekend as a coastal trough develops offshore. 47 


Aviation... think we're going to see IFR ceilings continue to 
transition into MVFR territory by middle to late morning and VFR for 
many areas during the afternoon. Cold front and associated rain showers will 
approach cll around 4pm, iah 9 PM and coast midnight. Much stronger 
winds...700-1500ft ceilings and Post frontal precipitation will continue 
overnight. Cannot completely rule out some rain/sleet mix at cll/uts 
after midnight but grounds should >32 so no significant surface impacts 
expected. 47
