Severe Weather Alert Descriptions

 Special Statement  Statement as of 3:46 PM CST on March 2, 2015


... Winter weather possible across north and central Texas
Wednesday afternoon through Thursday morning...

Rain will mix with and then changeover to a wintry mix... most
likely to be sleet... across much of the region by the afternoon
or evening hours Wednesday. Precipitation should come to an end by
Thursday afternoon as the upper level system moves east of the
region.

* Location... the areas most likely to see accumulations of ice or
sleet approaching one half inch are those along and southeast of
a line from Lampasas to Athens. However... all of north and
central Texas is likely to see at least some light wintry
precipitation during this event.

* Timing... we expect rain to transition over to a wintry mix
beginning along the Red River around mid-morning Wednesday
... across the metroplex shortly after midday and around
Waco/Killeen/Palestine by sunset.

* Precipitation type... mainly sleet... with some snow and freezing
rain possible.

* Accumulation and impacts... accumulations remain uncertain at
this time... but with temperatures dropping below freezing during
the afternoon it would take little to produce deteriorating Road
conditions and some travel delays by Wednesday evening.
Hazardous travel conditions are most likely along and southeast
of a line from Lampasas to Athens at this time.

* Alternate scenarios... the amount and duration of wintry
precipitation depend on how fast cold air moves into place on
Wednesday... the earlier the cold air is here... the more wintry
precipitation we can expect. Areas most likely to be impacted
may change in later forecasts and the timing of the cold air
into the region is the primary factor limiting confidence in how
much and how long wintry precipitation will fall during this
event.

Please monitor future forecasts regarding the potential for
winter weather across North Texas Wednesday through Thursday.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Fort Worth Texas 
327 PM CST Monday Mar 2 2015 


Discussion... 


A long wave trough extends from the Hudson Bay vortex 
southwestward into the Desert Southwest where it will remain 
anchored for a few days while the rest of the trough moves east. 
The trough is positively tilted and will kick a surface cyclone 
across the Central Plains on Tuesday and send another strong cold 
front through north and central Texas. 


Winds will veer overnight as low pressure deepens in the Lee of 
The Rockies. A warm front near the Texas coast will begin moving 
north with local winds veering southeast. The return of low level 
warm advection will result in scattered light rain...areas of fog 
overnight and temperatures holding near steady or slowly warming 
tonight. 


Tuesday will be much warmer and breezy but skies should remain 
mostly cloudy. Scattered showers are expected area wide most of 
the day. Instability for thunderstorms will be best over the 
northeast counties during the afternoon. Instability will weaken 
in the evening...thus thunderstorm activity will become more 
isolated overnight as the cold front moves across the Red River 
shortly after midnight. 


We feel the NAM series is too slow with wednesdays cold front and 
have sided with the GFS/European model (ecmwf) model solutions for this forecast. 
The front will work through the County Warning Area Wednesday morning with 
temperatures holding steady or slowly falling once it passes and 
strong north winds the rest of the day. Lift along the front and 
forcing for ascent from above will keep showers/rain going most of 
the day. As the depth of the cold deepens...rain will transition 
to a wintry mix of freezing rain and sleet...then to all sleet. 
There may be some snow mixed it as the precipitation starts to 
end...but it should not be the predominant precipitation type for 
this event. We expect this transition to begin along the Red River 
around middle morning Wednesday...across the metroplex shortly after 
midday and around Waco/Killeen/Palestine by sunset. 


The main area of our concern is the southeast portion of the 
County Warning Area...generally southeast of a Comanche to Canton line with focus 
on Waco/Killeen to Athens/Palestine...where we think sleet could 
accumulate up to 1/2 inch and freezing rain up to 1/10 inch. This 
is due to a strong frontogenesis signature around 700mb and the 
right- rear entrance region of a 200 knot upper jet over this 
region. We will be issuing a special statement with this package 
to highlight the potential for sleet/ice to cause hazardous 
impacts Wednesday night into Thursday. This is an evolving system 
and the actual location and magnitude of the sleet and ice will 
likely change some as new data is received. 


As for the metroplex...once temperatures fall to freezing or 
below...precipitation would begin to accumulate on mix-masters.. 
overpasses and bridges...followed by roadways shortly afterward. 
The intensity of the sleet and duration will govern how fast 
impacts develop during the afternoon/evening commute. If around 
one-tenth or more of sleet accumulates by dark...then impacts 
would last through the Thursday morning commute. 


The precipitation will be ending over the southeast counties by 
midday Thursday. Otherwise...it will remain dry and cold into 
Friday. The cold air will move east late Friday with winds 
returning to the south. This will bring warmer temperatures for 
the weekend and a slight chance of rain over the southeast 
counties. Another upper trough may pass across the region on 
Sunday which could bring slightly cooler temperatures for Sunday 
and Monday. 75

Aviation... 
/issued 1225 PM CST Monday Mar 2 2015/ 


For the 18z tafs...the duration of IFR ceilings and visibilities is the 
primary forecast concern. 


Cloud heights were generally ranging from 3 to 5 hundred feet 
above ground level across North Texas at noon/18z. Hrrr forecast 
soundings indicate shallow lift will persist in the lowest few 
thousand feet of the atmosphere today...which does not Bode well 
for the prospects of having cloud heights climb much throughout the 
day today. Despite the cloud cover...there is still some heating 
at the surface. Despite persistent northeasterly winds at the 
surface...there is no strong cold air advection...so think 
temperatures will rise to around 40 degrees or just above for 
today's high. However...recent widespread snow/sleet melt across 
the dfw area has left the ground very damp. Current thinking is 
that any increase in temperature will be met with an increase in 
dew point due to evaporation keeping ceiling heights more or less 
steady throughout the daylight hours today. 


For tonight...think that cloud heights and visibilities will tend 
to remain stable. A strong low-level jet is expected to develop by 
early tomorrow morning which should start to provide enough low- 
level warm air advection to lower the near surface stability 
profiles a bit. Even if we maintain some inversion...a smaller 
depth of the inversion combined with the stronger winds aloft 
should promote some better mixing that results in an increase in 
cloud heights towards 1000 feet above ground level. Went with a few hours of 
low-level wind shear in the tafs tomorrow morning to account for 
the low-level jet...and then slowly improved ceilings throughout the 
day on Tuesday. 


What to watch for...as dew points climb on the nose of the low- 
level jet and warm air increases in intensity...there is some 
potential for advection fog if near surface winds can remain 
decoupled from the influence of the low-level jet. Confidence in 
this was not high enough to bring visibilities down to one half 
mile or below tomorrow morning with the onset of the stronger warm 
air advection...however this is something we'll be watching 
closely over the next 12-18 hours. Cavanaugh
