SURFACE HIGH PRESSURE AND IT'S COOLER AIR IS NOW WELL TO OUR EAST
AND IS SPILLING ON THE MID ATLANTIC COAST. OUR RETURN FLOW OFF
THE GULF OF AMERICA IS LIGHT SSE ALREADY WELL ESTABLISHED UP TO
5-KFT WITH AN INVERSION. THERE IS JUST ENOUGH MOISTURE FOR A FEW
MORNING DECKS IN CENLA, BUT MOSTLY FEW TO SCATTERED STRATOCU
AREAWIDE DURING PEAK HEATING, AS OUR SURFACE WINDS VEER TO S/SW
AND BECOME A LITTLE GUSTY TO NEAR 20 MPH.
ALOFT, A DEEP NORTHERLY FLOW WITH 100KT+ IN THE BASE OF THE LONG
WAVE TROUGH, WHICH EXTENDS FROM DEEP E TX UP ACROSS THE OHIO
VALLEY INTO EASTERN CANADA. LOTS OF CIRRUS WILL BECOME A FIXTURE
NOW UNDER THE BUILDING UPPER RIDGE OVER AZ 590DAM NOW WITH MODELS
KEEPING IT NEAR THAT HEIGHT FOR THE NEXT COUPLE OF DAYS WHILE
DRIFTING EAST. THEN FLATTENING OUT AND RETROGRADING A BIT WITH
THE NEXT CANADIAN AIR MASS POURING INTO THE U.S. BY LATE WEEK WITH
1042MB FRIDAY MORNING. THIS FRONT WILL PUSH DOWN THE MS RIVER
VALLEY AND TOUCH AND GO THE 1038MB CORE OVER ST. LOUIS MO SATURDAY
MORNING. SO THATS OUR CLOSEST APPROACH, A THIS QUICK SHOT OF COOL
AIR ONCE GIVE US A NORMAL DAY TEMPERATURE WISE VIA THE MOISTURE
STARVED BACKDOOR APPROACH METHOD.
MEANWHILE, THIS UPPER RIDGE IS SPUN UP BY THE DIGGING LONG WAVE
OVER THE E PACIFIC. HOWEVER, ONCE THE RIDGE COLLAPSES LATE WEEK,
THE FIRST SHORT WAVE MOVES ONTO THE W COAST EARLY NEXT WEEK AND
WILL BRING US THE APRIL SHOWERS AND THUNDERSTORMS. BEHIND THE
FIRST PUSH THE MODELS VARY ON A CORE UPPER LOW DROPPING DOWN IN
THE PATTERN TOWARD CA AND WILL TRANSLATE INTO MORE DEEP SOUTHWEST
FLOW ALOFT FOR US IN THE NEXT COUPLE OF WEEKS, PROMISING THE RAIN
WE NEED AND SEE IN THE CPC DAYS 6-10 WITH NEAR AVERAGE
EXPECTATIONS, AND THEIR DAYS 8-14 WITH ABOVE AVERAGE DAILY
AMOUNTS. /24/
