... Dense fog advisory now in effect until noon CST today...

* visibility... 1/4 of a mile or less in some areas.

* Impacts... driving will be hazardous in reduced visibilities.

Precautionary/preparedness actions...

A dense fog advisory means visibilities will frequently be
reduced to less than one quarter mile. If driving... slow down...

 Special Statement  Statement as of 6:07 am CST on March 3, 2015


... A wintry mix is expected Wednesday evening through Thursday
morning...

Another strong Arctic cold front will plunge across south central
Texas during the day on Wednesday. Temperatures will rapidly fall
after the frontal passage. Freezing temperatures are expected to
begin to filter into The Hill Country Wednesday evening and spread
to near Highway 90 or north of a del Rio to San Antonio to
Giddings line by Thursday morning. A sleet and freezing rain mix
will develop Wednesday evening across The Hill Country and then
transition to a sleet and snow mix by Thursday morning for areas
north of Highway 90. Areas in The Hill Country and along the I-35
corridor northeast of San Antonio will have the best chances of
accumulating ice with impacts. Temperatures will warm to above
freezing by midday on Thursday with any remaining precipitation
being all rain.

Those residing in or visiting south central Texas should monitor
the forecast for the latest information and updates regarding this
potential winter weather event.

NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Austin/San Antonio Texas 
957 am CST Tuesday Mar 3 2015 


Update...fog persists across The Hill Country and locations along 
the I-35 corridor eastward. Some locations are still reporting 
dense visibilities...and have decided to extend a good portion of 
the dense fog advisory through noon. 


Jr

Previous discussion... /issued 537 am CST Tuesday Mar 3 2015/ 


Aviation... 
poor flying conditions will continue through this taf period with 
either IFR or LIFR expected. All terminals were LIFR for most of 
the night with del Rio lifting to IFR around 09z. The San Antonio 
sites have now begun to bounce between IFR/LIFR as shower have 
formed over the I-35 corridor. Expect improved IFR visby/ceilings with 
the rain showers...with LIFR conditions between showers at Sat/ssf 
through the morning hours. 


Models show a slow improvement through the afternoon at the I-35 
terminals with ceilings lifting to IFR and the fog dissipating. The 
period of IFR will be short lived as ceilings lower again after sunset 
and more fog is expected to develop. The I-35 terminals will 
return to LIFR conditions between 03z and 06z and remain socked in 
through the night. Rain chances increase during the day tomorrow 
so have included prob30 groups at the end of the taf for the 30 
hour tafs sites to reflect this. Winds would be light out of the south 
by later today and remain southerly through tomorrow morning. 


Del Rio is expected to see ceilings rise this afternoon with a few 
breaks in the clouds possible. By 21z drt should be VFR for a few 
hours under overcast skies. IFR ceilings return to drt by 06z.

Previous discussion... /issued 448 am CST Tuesday Mar 3 2015/ 


Short term (today through wednesday)... 
areas of dense fog with patchy drizzle continued across much of 
south central Texas early this morning due isentropic lift with 
southerly winds just of above the persistent cool surface ridge. 
Finally expect the long anticipated significant warm up today as 
the surface trough along the coast weakens allowing for southerly 
flow to spread across south central Texas. The dense fog will 
persist through middle morning with some fog and drizzle lingering 
into the afternoon. Isentropic lift decreases as southerly flow 
takes hold allowing for some sun and the warmer temperatures. We 
will still be below average with the coolest temperatures along 
the I-35 corridor as surface ridge lingers there the longest due 
to cool air banking up against the Escarpment. The lower level 
jet strengthens tonight allowing some streamer showers to develop. 
Another strong cold front...currently extending from the Dakotas 
into northeast Colorado...will surge across central and south 
central Texas during the afternoon. A favorable upper level jet 
position...moisture convergence along the front and instability 
indicate some thunderstorms are possible. An abrupt drop in 
temperatures of 15 to 25 degrees is expected with the frontal 
passage as strong cold advection spreads across our area. 




Long term (wednesday night through monday)... 
strong cold advection as surface high builds into our area will be 
ongoing Wednesday night in the wake of the frontal passage. Upward 
motion from favorable upper level jet position passing overhead 
and middle level shortwave to our west will continue precipitation 
chances. Forecast soundings show a freezing rain and sleet mix 
developing over The Hill Country in the evening...transitioning to 
a sleet and snow mix while spreading to remaining areas north of 
Highway 90...including the I-35 corridor from San Antonio to the 
northeast. Ice accumulations of less than one quarter inch may be 
possible across The Hill Country. However...there is some model 
uncertainty on amount of moisture that will be available as drying 
will take place. A strong pressure gradient will generate windy 
conditions. A Wind Advisory may be needed. Temperatures fall below 
freezing across the northern areas by Thursday morning. Some rain 
lingers Thursday afternoon into evening across the southeastern 
areas as the jet moves off to the east while temperatures rise 
above freezing all areas. A more widespread freeze is likely 
Friday morning as clouds decrease due to continued drying and a 
cold surface ridge over our area. The middle level shortwave reforms 
into a low a little further west and then moves across southern 
Texas this weekend. Moisture and upward motion increase leading to 
slight chances of rain on Saturday into Sunday. Although...the 
surface ridge persists this weekend into early next week... 
temperatures will be above freezing and no winter precipitation 
is currently expected. Some recovery in temperatures is expected 
by early next week. However...they will remain below average.
