March: Comfortable Weekend Weather & Warming Trend

[davidiowx]

Some pretty loud thunder here as well. Winter Storm Warnings should be issued to Fort Bend I would think. This is going to be an interesting night if the rain doesn't warm the surface. Wow so unpredictable.

[txsnowmaker]

Impressive. That cell I keep taking about appears to be gaining a little strength as it moves into southwest Harris County.

[nuby3]

Very strong cell still holding up and appears that it is about to cross into southwest Harris County.

dropping a half an inch as it passes all by itself. awesome night ahead

[Mr. T]

You can see the main disturbance starting to come through from the South Texas radar.

Was just about to post this...

Some people will be confused once this initial band moves out. That's our main event come daybreak...

This current stuff isn't helping anything, tho

[txsnowmaker]

Tim Heller said that the cell is right over Cinco Ranch right now. Anybody in that part of town?

10:00 PM Update from Jeff:

High impact ice storm likely.

Radar continues to show extensive rapid development of moderate to at times heavy freezing rain and sleet from northern Harris County westward to west of San Antonio. With surface temperatures already at or below freezing across areas along and north of I-10 freezing rain and ice accumulation is likely.

Given increased duration of the event in combination with heavier precipitation rates requires the adjusting of ice amounts into the .10-.25 inch range along and north of I-10 with isolated amounts possibly as high as .30 of an inch. Continue to be worried about the incoming convective cells and their ability to put down some really good freezing rain rates.

This will cause significant travel impacts across all the warning area starting within the next few hours and lasting well into midday Tuesday. Travel by Tuesday morning will be extremely hazardous with ice likely on all bridges and overpasses and even some surface streets.

Ice amounts may be great enough in isolated areas to result in some loss of tree limbs and power lines leading to isolated power outages.

I have already measured a tenth

[spadilly]

I hadn't heard thunder in so long that the wife and I looked at each other in disbelief.

Ice pellets and thunder here in spring branch.

Both the 0z GFS and the latest (1z) HRRR short-range model increase moisture amounts for the Austin/SC Tx area overnight and show between .25" and .5" of precip for the Houston area. Definitely worrisome.

The rain here is starting to freeze on my patio grill, also going from drizzle to light rain.

Question....is the rain/moisture we're getting now helping to cool the warm layer in the upper atmosphere? Is the rain we're getting now helping any at all?

Thanks Mr T. That's the one--heading right through the heart of Houston!

[srainhoutx]

Numerous reports of sleet, graupel and freezing rain coming in across Northern Harris County.

Raining in kingwood

Question....is the rain/moisture we're getting now helping to cool the warm layer in the upper atmosphere? Is the rain we're getting now helping any at all?

Well the evaporation that is occurring in the area is an endothermic process meaning it is cooling the atmosphere. That is what we commonly associate with the wetbulb temp. Now what does happen with stronger storms is the precip can actually bring warmer temps down to the surface. Something we will need to keep an eye on as we go into the night but I suspect this won't be much of an issue.

[srainhoutx]

Ice coating car tops and metal surfaces in NW Harris County.

[Mr. T]

Officially freezing rain in Kingwood with a temp of 31. A nice glaze on exposed surfaces, cars, etc...

[Charlster]

I live in Angleton. Can we expect any ice down this far? I wasn't expecting this weather at all.
