[srainhoutx]

12Z NAM suggests a rather strong line of storms along and ahead of the Cold Front tomorrow...doesn't look too boring wxdata...

Appears that we are going to make a run at some freezing morning lows in the Metro Area...

Are these two freezes during Saturday night-Sunday morning and Sunday night-morning likey to be the last freezes that southeast Texas receives for this month or is another one predicted to come later on in this month and perhaps even one prior, during, or after Easter?

[sleetstorm]

How about this, southeast Texas gets an additional two cold waves for this weekend & for the initiation of the new work week, with the feasibility at getting two consecutive frosts or freezes. sigh Hey, though frosts and freezes are not good for any fresh new leaves and flowers, all of us in this weather forum need to be truly thankful that it not predicted to be a hard freeze or even a very hard freeze, 20's or 10's for that would just be utterly horrible for any trees, shrubs, and small plants, excluding evergreens, setting them back x number of days if not weeks. Or, do some of you not concur with this?

It'll be hard to get to freezing Sunday morning with a low overcast that'll probably hang around until Sunday afternoon. With the upper low over NE TX, wrap around clouds will limit lows Saturday night and Sunday highs. May see upper 30s to 40 Sunday morning and a high closer to 50 than the upper 50s on Sunday with the clouds. Interesting that the Houston AFD says wrap around clouds most of Sunday but the zone forecast says clear to partly cloudy.

WXman57 I am so ready for the real Spring. Up here in Dallas this weekend so I might get lucky and see more snow.

You and me both Katdaddy! Take some pics.

Well, let's see if the 18Z GFS sees any spring on the horizon. Here are a couple of meteograms. As you can see, more days above 70, but nothing near 80 for the next 2 weeks. That's unbelievable, only a couple of 80 degree days through early April. And I do think Sunday will be overcast much of the day, so Monday should be the colder morning (35).
