The front has moved back north of me and sun is peeking out - it's starting to feel pretty muggy outside.

You can really see the main cold front barreling down on the visible satellite loops, too.

the Updated SPC Outlook now includes a Hatched area for large and possibly damaging Hail particularly across potions of S Central, Central and the Western zones of SE Texas. IF the cap erodes as expected this afternoon, that damaging hail potential may shift East toward Louisiana.

Some excitement ahead for Louisiana. This event looks more like a bust for HGX and CLL area if the cap holds. Big wind shift ahead... The recent rains preclude fire danger, so we have that going for us.

WE are currently clear, beautiful blue sky, 81F and sunny. What a difference a few miles makes!

Thunder and rain in Sharpstown. We seem to be on the west side of the mass. Glad I didn't have to work downtown today!!

storms heading to east side of town

don't need the hail, but could have used some rain to get rid of the pollen

That meso cluster is hanging together. May move towards Victoria. Small, severe storm still popping near Sugarland.

Wow.

Big-time bust.

Nothing for me, yesterday. Barely enough rain to wet the ground. Heavy storms missed me on all sides.

Only clouds that teased down here by the Bay.

Its a little chilly out there today. I am sure Wxman57 is in hibernation mode. The upper 80s and humidity was very nice in FLA last week and get home just in time for the last few days of Winter with weather to go with the days.

Red Flag Warning for elevated fire risk due to gusty N and NW winds with low humidity this afternoon. Sunny and breezy this with highs in the low 60s. Thunderstorm chances to return to SE TX mid-week with a severe weather threat for NE TX, SE OK, W AR, and SW MO. This area will become more refined over the next few days.

Impressive advection into CLL and HGX.

Gusty northerly winds 20-35 mph here with gorgeous blue skies and temps in the 50s. DP in the upper 20s with 29% RH. I'd love to bottle this up for most of the year. A/C and water off and utility bill low. The red oaks and grass though are still about 3 weeks ahead of schedule. Live oak showing robust growth. Couldn't be better. Am threatening to plant another tree - possibly Chinquapin Oak.

Frost/freeze in the Hill Country. Mid to upper 30s tonight from CLL to Conroe. Conroe may see some light frost on the ground in the wee hours.

35F at the house this morning and 31F in Conroe and Lufkin. Brrr...

Looks like another example of the NWS not issuing any freeze or frost advisories for the affected areas so late in the season...
