I've had enough of the Texas rain wreaking havoc on my vacation plans.

Many rivers in Oklahoma at major flood stage: Advanced Hydrologic Prediction Service: Norman

Remember all that moisture in central U.S... look where its travelling now... Followed the Trough axis now on top of the ridge. New England going to get some rain.. if the dry air doesn't gobble it up.

If that ridge wasn't so far north in the East, then I'd be getting the rains. Hot and dry inside it.

That must be why it's been wet in the upper Midwest and and Great Lakes.

NWS issued a moderate risk today. Possibility of a derecho forming.



...NORTH TX AND SOUTHERN OK...
MORNING WATER VAPOR LOOP SHOWS A COMPACT...PROGRESSIVE SHORTWAVE
TROUGH OVER SOUTHWEST TX. THIS FEATURE IS FORECAST TO MOVE RATHER
QUICKLY NORTHEASTWARD ACROSS CENTRAL TX THIS MORNING...AND INTO
NORTH TX/SOUTHERN OK LATER TODAY. A CLUSTER OF STRONG THUNDERSTORMS
HAS FORMED IN WEST TX...WITHIN THE ASCENT REGION AHEAD OF THE
SHORTWAVE TROUGH. THESE STORMS ARE EXPECTED TO CONTINUE TO ORGANIZE
AND INTENSIFY THIS MORNING AS DAYTIME HEATING RAPIDLY DESTABILIZES
THE AIR MASS DOWNSTREAM OF THE STORMS. MOST OVERNIGHT CAM SOLUTIONS
ARE CONSISTENT IN ORGANIZING THIS CLUSTER OF STORMS INTO A BOWING
MCS /POSSIBLE DERECHO/ THAT WILL TRACK ACROSS NORTH TX AND SOUTHERN
OK LATER TODAY. GIVEN THE FAST AND NEGATIVELY-TILTED NATURE OF THE
UPPER TROUGH...THE STRONG MID LEVEL WINDS THAT ARE FORECAST TO PASS
ACROSS THE REGION...STEEP MID LEVEL LAPSE RATES...AND AMPLE
CAPE...HAVE UPGRADED THIS REGION TO A MODERATE RISK. VERY LARGE
HAIL AND POTENTIALLY WIDESPREAD DAMAGING WINDS ARE POSSIBLE.
TORNADO PROBABILITIES HAVE ALSO BEEN RAISED FOR THE RISK OF DISCRETE
SUPERCELLS FORMING AHEAD OF THE MCS AROUND PEAK HEATING WHEN
INHIBITION WILL BE WEAKEST...AS WELL AS FOR THE RISK OF QLCS
SPIN-UPS ALONG THE LEADING EDGE OF THE MCS. STORMS SHOULD SPREAD
EAST-NORTHEASTWARD INTO AR AND NORTHERN LA DURING THE EVENING WITH A
CONTINUED RISK OF DAMAGING WINDS AND HAIL.

from SVT's early sum-up of the May weather.



this excerpt caught my attention.

so far, May has been a wet and cool history, yet the average temperature is almost completely normal.

lol, the failure in using an ancient normal period. i'd say 99.9% of all people would say this has been a cold may, and the 1981-2010 normal would testify that's the case too. besides, most of the country has been clearly below even the 61-90 normal.

Hmm. If this continues I wonder if clouds could hold down the hot weather from being as extreme.

Good point and that is probably why they have been lowered and no more 90s. Also, looking very wet first week of June. Probably because that northern edge shifts down to us and we get the moisture flow. Not sure.

NWS NY

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...

SUMMERTIME PATTERN IN PLACE THIS TIME FRAME. UPPER RIDGE OVER THE
EAST COAST WILL GIVE WAY TO WEAK TROUGH/SHORTWAVE AS IT TRAVERSES
EASTWARD WEDNESDAY NIGHT AND THURSDAY. IN TIME...RIDGE WILL
REESTABLISH ITSELF LATE IN THE WEEK AS JET RETREATS NORTHWARD.

THE JET EVENTUALLY SAGS SOUTH NEXT WEEKEND AS NORTHERN STREAM TROUGH
TRACKS ACROSS CANADA...RESULTING IN LOWERING HEIGHTS AND MORE OF A
ZONAL FLOW ACROSS THE NORTHEASTERN UNITED STATES.

AT THE SURFACE...BERMUDA HIGH REMAINS IN PLACE WITH PERSISTENT SW
FLOW ACROSS THE EAST COAST
