SW LA/SE TX Winter 2012-2013

[southerngale]

Spring just won't stick around, will it? It looks like I might see 30s again later this week! That's pretty unusual for SE TX in mid to late April. Btw, with the storms April 10th overnight into the 11th, I got hail at my house.

It's going to get cold again. Jeff Lindner's email:

Powerful late season cold front currently extends from east of Dallas to Waco to just west of Austin.

Strong cold front is moving SE at 30-40mph and should reach our NW counties by 900-1000am. Line of strong thunderstorms is found along the boundary north of Waco with a line of showers and weaker storms extending south of Waco to SW of Austin. Overnight soundings continue to show strong capping in place over SE TX with moisture trapped below this inversion in the mid-levels. The abundance of low level moisture is resulting in widespread very light rain and drizzle across the area. Strong front will cross the area today with showers and thunderstorms developing along and behind the boundary. Severe threat will be limited to our far NE counties…from Lake Livingston northward as capping looks to hold for the most part across the rest of the area.

Bigger impact will be a significant drop in temperatures as the front passes from the warm and muggy upper 70’s quickly into the 50’s under strong NW winds. This front will be similar to the front last Wednesday with respect to the temperature drop. Clouds clear on Friday, but cold surface high pressure will only allow warming into the 60’s even with strong April sun.

Record cold low temperatures will be possible on Saturday morning as clear skies and light winds allow excellent cooling conditions. Lows will likely range from the upper 30’s to lower 40’s across the region which is 20-25 degrees below normal for this time of year.

Here we go again. Jeff's morning email brings in the COLD again. Records are in jeopardy on Friday and Saturday.

Powerful late season cold front will arrive on Thursday resulting in potentially record setting cold on Friday and Saturday.

Very cold Canadian air mass for this time of year is surging down the plains this morning and will reach TX this evening and move off the TX coast Thursday afternoon. Today will feature warm and humid conditions ahead of this front with highs in the low to mid 80’s under weak south winds. The upper level low responsible for the scattered storms on Wednesday has moved into LA this morning with a drier and subsident air mass in place across SE TX. Would not rule out an isolated shower or storm east of I-45 today…but the key word is isolated.

Strong front will reach our NW counties by sunrise and push off the coast by mid afternoon. High temperatures will be ahead of this boundary in the low to mid 70’s with a quick fall into the 60’s and possibly 50’s under gusty north winds. Chances for rain look marginal as best dynamics are well north of the region and drying on the backside of the LA upper level low is reducing the moisture profile. Winds also shift to the N prior to the front reaching the area which reduced surface convergence. Expect a thin line of showers and maybe an isolated thunderstorm along the boundary.

Cold air mass surges into the region Thursday night with lows Friday morning in the mid 40’s. Low temperature records are in the upper 40’s and it appears that these will be broken. A few all-time monthly low temperature records look in jeopardy also either Friday or Saturday mornings. Highs on Friday will struggle to reach 70 degrees under conditions cold air advection. Lows Saturday morning may be cooler in the lower 40’s with clear skies and light winds.

Slow warm up begins Sunday with winds only slowly turning back off the Gulf by early to mid next week. Unseasonable cool and dry for early May.

And there is another cold front coming next week?
