Suprise rainfall
I heard a few clashes of thunder and it has been raining for a while near Downtown Houston. Was this expected?

looks like the SPC thinks we could have a very active morning tomorrow...

Lots of SE Texas has a 30% severe risk!

WELL-DEVELOPED FORWARD PROPAGATING MCS WILL LIKELY BE ONGOING AT 12Z

Well now they lowered the rain chances tonight to 30% and the same for tomorrow...
This Afternoon: A 30 percent chance of showers and thunderstorms. Some of the storms could be severe. Partly cloudy, with a high near 92. West wind around 5 mph.
Tonight: A chance of showers and thunderstorms before 9pm, then a chance of showers and thunderstorms after 1am. Some of the storms could be severe. Partly cloudy, with a low around 71. Southeast wind 5 to 10 mph becoming southwest. Chance of precipitation is 30%.

yeah, I don't know why they lowered it though. The afternoon discussion looked pretty promising for storms tonight/tomorrow and with a decent severe risk from the SPC, a 30% rain chance sounds too low. I bet they will up the chance later tonight or tomorrow once something actually forms to our west and they get a better handle on the situation.

I see those at college station...where i'm at right now! Let's hope these storms stay to the west of cs so the cajuns can win their regional!

Still at 30% according to the SPC ( http://www.spc.noaa.gov/products/outloo ... 30_any.gif ). We will not have another update for tomorrow though for about 8-9 hours...but I wouldn't expect much of a change. According to the NWS and SPC an MCS should move through here sometime tomorrow morning coming from the west.Yankeegirl wrote:I think they lowered the chance of severe storms tomorrow...

I think that is what the SPC is predicting to happen (for those to become a squall line and then move through). I guess we will see what happens overnight..Yankeegirl wrote:There are also some storms popping again out in far west Texas...Wonder if those will hold together for later tonight/tomorrow morning...?

Large MCS to affect a large part of C and SE TX tonight.
Old outflow boundary from MCS last night extends from BPT to Spring to KCLL where numerous severe storms have erupted this afternoon over the N half of SE TX and over much of C TX. Large complex of storms has formed over far WC TX where MCS formation is likely in the next few hours.
Main threat will be wind damage and hail as this complex moves into C TX after midnight and through SE TX after midnight (more likely toward 300am-600am).
NW flow aloft will remain for the next 2-3 days with disturbances in the flow sparking nightly MCS activity over TX and old outflow boundaries focusing convection during the afternoon hours.
LArge summer like ridge gains control toward the end of the week with the heat really cranking up.
