I had .98" here. I was pretty happy about that

I had .98" here. I was pretty happy about that

we had just shy of 2" per a local weather station - loved it !

[srainhoutx]

A nice and quiet weather week ahead before the next W Coast trough moves inland bringing a chance of showers/storms beginning next weekend to parts of the Panhandle/N TX and Southern/Central Plains. Meanwhile, get out and enjoy this Chamber of Commerce weather. Remember that this time last year we were bone dry and already in the 90's.

VALID 251200Z - 301200Z

...DISCUSSION...
00Z ECMWF/GEFS GUIDANCE ARE IN AGREEMENT WITH THE GENERAL
PERSISTENCE OF AN AMPLIFIED PATTERN MUCH OF THE PERIOD...HIGHLIGHTED
BY A SLOW GENERAL EASTWARD PROGRESSION OF AN UPPER TROUGH OVER THE
ROCKIES/TOWARD THE PLAINS FROM MID-WEEK ONWARD /DAYS 4-7/.

INITIALLY FOR DAY 4/WEDNESDAY...AT LEAST SOME SEVERE THREAT MAY
EXIST ACROSS PORTIONS OF THE MIDWEST/OH VALLEY IN ASSOCIATION WITH A
SOUTHEAST MOVING SURFACE LOW/COLD FRONT AND PARENT LOW AMPLITUDE
SHORTWAVE TROUGH. A FEW STRONG TSTMS MAY ALSO BE POSSIBLE FOR
PORTIONS OF SOUTHERN CA AS AN UPPER TROUGH/ASSOCIATED FRONT MOVES
INLAND ON DAY 4/WEDNESDAY.

THEREAFTER...SEVERE POTENTIAL SHOULD INCREASE ACROSS PORTIONS OF THE
PLAINS AS THE UPPER TROUGH APPROACHES THE REGION...ALTHOUGH
INITIALLY LIMITED MOISTURE RETURN AND UNCERTAIN SPECIFIC EVOLUTION
OF THE UPPER TROUGH PRECLUDE ANY 30 PERCENT SEVERE AREAS AT THIS
TIME. NONETHELESS...CURRENT THINKING IS THAT AT LEAST
ISOLATED/POTENTIAL SLIGHT RISK-CALIBER SEVERE THREATS COULD EXIST
DAY 5/THURSDAY ACROSS PORTIONS OF THE SOUTH-CENTRAL HIGH
PLAINS/PERHAPS ROCKIES FRONT RANGE...AND INTO DAYS 6-7
FRIDAY/SATURDAY ACROSS THE SOUTH-CENTRAL PLAINS POTENTIALLY
INCLUDING PORTIONS OF KS/OK/NORTHWEST TX AND POSSIBLY THE ADJACENT
MO VALLEY.

[srainhoutx]

Not so sure I'm buying that dull comment, Ed. Guidance is suggesting a frontal boundary nearing the region on Saturday into early next week before stalling. As we saw with the last front/storm system, we may just end April with a bit more rain and that's not a bad thing, IMO. It is certainly much better than last year when day after day of never ending hot and dry brought nothing but boredom to everyone, weatherwise.

[tireman4]

Amazing day for running. Just amazing. May they all be this perfect. ( Yeah, I know, hot and humid and disgusting are coming...sigh)

[Ptarmigan]

Glass half full, when life hands one boring weather, look for 32ºC 850 mb temps in Western Texas/Border Regions!

Looks like the heat wave from Death Valley is coming.

whats the deal with the mild weather. When is summer going to arrive? Last year we hit the 90s already. This year it doesn't look like it will get hot at all? Has the move away from La Nina caused this? When do y'all see the heat arrive with the humidity?

whats the deal with the mild weather. When is summer going to arrive? Last year we hit the 90s already. This year it doesn't look like it will get hot at all? Has the move away from La Nina caused this? When do y'all see the heat arrive with the humidity?

Most likely due to Arctic Oscillation (AO) and North Atlantic Oscillation (NAO). A positive AO and NAO keeps the cold Arctic air to the north due to the jet stream. Also, the jet stream is still feeling the effect of La Nina. Also, the Northeaster created sinking air to the west.

[MontgomeryCoWx]

Kids shivering? LOL, kids need to toughen up if 50s and 60s have them shivering.

I could go for some 30s about right now.

[srainhoutx]

Guidance is suggesting some short wave activity crossing the Lone Star State on Sunday into Monday. While the severe weather appears to be well to our N across the TX Panhandle/N TX and OK into KS, there may be a chance for scattered showers Monday to end the month of April. Perhaps someone can start a Topic for May...all eyes will begin to turn to the Tropics in the not too distant future I suppose...

[srainhoutx]

Morning e-mail from Jeff:

A slight chance of showers and thunderstorms this afternoon mainly over our western and northern counties.



Weather pattern will remain one of persistence for the next several days, with the best chances for rainfall today…and that is not all that great. Tail end of a short wave over the central plains moving into the mid Mississippi Valley this morning will provide a bit of lift across the area today. Air mass, while currently capped, will become increasingly unstable with surface heating. Capping should gradually erode especially over our northern counties this afternoon and this coupled with an unstable air mass may lead to a few strong to severe thunderstorms. Lack of any sort of surface boundary makes initiation somewhat questionable and weak shear suggest loosely organized thunderstorms, so factors appear about 50/50 if we will even see any activity. Southward over the rest of the area, capping will be slower to erode as this area is closer to the sub-tropical ridge aloft, in fact most of the coastal areas will see little if any chance of rainfall today.



For the rest of the week, ridging begins to rebuild over the state with increasing heights aloft and capping in the mid levels putting the “lid” on any chances for rainfall. SE flow off the Gulf of Mexico will be maintained with warm and very humid conditions into next weekend. Highs will run in the mid to upper 80’s each day with lows in the lower 70’s.



Toward the end of the week, a disturbance currently located over southern FL will track WNW toward the central US Gulf coast states on the southern side of the sub-tropical ridge…an almost summer like pattern. Current thinking is that ridging building over the western US will keep most if not all of the moisture with this feature east of TX, so a continuation of the same into next weekend.



Gusty winds of late should back down some this week, it will still be breezy in the afternoon hours, but not the 25-35mph winds of late last week.
