Significant May Rainfall
YIKES! Take a look at the radar estimated rainfall from across the southern part of the country. The pink and purple colors below suggests nearly 12″ to 24″ of rain over the past 26 days! Many locations have not only recorded their wettest May on record, but they have also recorded the wettest month on record, including Oklahoma City, OK and Wichita Falls, TX.
Oklahoma City, OK: 18.97″ of rain through May 26th. Not only the wettest May on record, but also the wettest month on record beating the 14.66″ of rain set in June 1989
Wichita Falls, TX: 14.53″ of rain through May 26th. Not only the wettest May on record, but also the wettest month on record beating the 13.22″ of rain set in May 1982.
Weather Outlook
Our wet ways continue as another storm system looks to develop over the next couple of days and push east through the Central U.S.. Keep in mind that some of the shower and thunderstorm activity could some with some severe weather.
Severe Threat Wednesday
…SUMMARY…
SEVERE STORMS ARE POSSIBLE TODAY ACROSS PARTS OF THE NORTHERN MID
ATLANTIC COAST REGION INTO NORTHERN NEW ENGLAND…AS WELL AS PARTS
OF THE UPPER OHIO VALLEY AND LOWER GREAT LAKES REGION…AND PORTIONS
OF THE CENTRAL HIGH PLAINS INTO THE SOUTHERN PLAINS.
…OHIO VALLEY…
MORNING WATER VAPOR LOOPS SHOW A SHORTWAVE TROUGH MOVING ACROSS
IA/MO. A PERSISTENT CLUSTER OF THUNDERSTORMS IS ASSOCIATED WITH
THIS TROUGH OVER SOUTHEAST MO. EARLY VISIBLE SATELLITE IMAGERY
SHOWS RELATIVELY CLEAR SKIES DOWNSTREAM OF THE CONVECTION…WHICH
SHOULD ALLOW RAPID HEATING AND DESTABILIZATION. PRESENT INDICATIONS
ARE THAT THIS CLUSTER OF STORMS WILL INTENSIFY BY LATE MORNING OVER
SOUTHERN IND/WESTERN KY AND TRACK NORTHEASTWARD ACROSS OH INTO
WESTERN PA. MLCAPE VALUES OVER 1500 J/KG AND 40-50 KNOTS OF MID
LEVEL FLOW SUPPORT A RISK OF LOCALLY DAMAGING WINDS AND HAIL IN
THESE AREAS.
…MID ATLANTIC REGION INTO NEW ENGLAND…
A BAND OF SHOWERS CURRENTLY EXTENDS FROM WESTERN NY SOUTHWARD INTO
WV. THIS WEAK CONVECTION IS ASSOCIATED WITH A LEAD SHORTWAVE TROUGH
THAT WILL MOVE EASTWARD INTO PARTS OF THE MID ATLANTIC REGION AND
NEW ENGLAND LATER TODAY. STRONG HEATING IN THIS REGION COUPLED WITH
DEWPOINTS IN THE 60S WILL HELP YIELD MLCAPE VALUES OVER 1000 J/KG.
MOST CAM SOLUTIONS SHOW SCATTERED THUNDERSTORM DEVELOPMENT ALONG
THIS CORRIDOR BY MID AFTERNOON. LOW LEVEL AND DEEP LAYER SHEAR
PROFILES ARE FAVORABLE FOR ORGANIZED/BOWING STORM STRUCTURES CAPABLE
OF LOCALLY DAMAGING WINDS. ANY STORM THAT CAN REMAIN DISCRETE IN
THIS REGION WOULD POSE A MARGINAL RISK FOR A TORNADO AS WELL.
…CENTRAL/SOUTHERN HIGH PLAINS…
STRONG HEATING WILL OCCUR ONCE AGAIN TODAY OVER PARTS OF EASTERN
CO/WESTERN KY AND SOUTHWEST NEB…SOUTHWARD INTO TX AND WESTERN OK.
SIMILAR TO YESTERDAY…MODERATE CAPE VALUES AND A BREAKABLE CAP WILL
RESULT IN ISOLATED TO SCATTERED THUNDERSTORMS ALONG THE DRYLINE.
THE HIGHEST PROBABILITY OF STORMS APPEARS TO BE FROM SOUTHWEST NEB
INTO NORTHWEST OK. STRENGTHENING LOW LEVEL WINDS THIS EVENING AND
STEEP LAPSE RATES WILL PROMOTE A RISK OF SUPERCELLS CAPABLE OF
HAIL…DAMAGING WINDS…AND ISOLATED TORNADOES.
Severe Threat Thursday
Severe Threat Friday
More Heavy Rain
Unfortunately, more heavy rain is on the way for some of the same areas that have been so hard hit as of late. The 5 day rainfall forecast suggests an additional 2″ to 3″+ possible through early next week.
