This Hazardous Weather Outlook is for portions of Deep South
Texas.

.DAY ONE...This Afternoon and Tonight

Heat index values are likely to reach 100 to 105 degrees across 
portions of deep south Texas this afternoon.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

the lower 90s Monday afternoon across the Rio Grande valley into 
the upper 50s to the lower 60s Monday evening with wind chill 
index values near 50 degrees in the wake of a strong cold front. 
The sharp change in temperatures after unseasonably warm

persons unable to adapt to the abrupt temperature change. Strong 
north winds may gust to near 35 mph or higher late afternoon into 
early evening, which could cause minor damage to lightweight

ahead of the cold front across portions of deep south Texas. Wind
gusts to near 40 mph as well as occasional to frequent cloud to 
ground lightning strikes can be expected with storms.

into the upper 40s to middle 50s with some areas seeing wind chill
values as low as the lower 40s early each day. This may continue 
or exacerbate problems for persons unable to adapt to the sharp 
temperature change. Wind gusts mainly along and east of highway 77
could reach 30 to 35 mph and cause minor damage to unfastened 
lightweight objects. Wind advisories may be needed for the coastal
counties of deep south Texas. Showers and isolated thunderstorms
may produce locally heavy rainfall across portions of deep south
Texas Tuesday through Wednesday which may cause minor flooding in
locations with poor drainage.

Wednesday Night through Thursday: Showers and isolated
thunderstorms may continue to produce locally heavy rainfall
across portions of deep south Texas which may cause minor 
flooding in locations with poor drainage. Wind gusts above 30 mph
