Damaging Winds in Alabama, April 25, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
337 PM CDT SAT APR 25 2015

.DISCUSSION...

THE SECOND ROUND OF CONVECTION HAS PUSHED INTO ALABAMA FROM
MISSISSIPPI. THE CORE OF THE MCS WILL TRACK EASTWARD ALONG THE
IMMEDIATE GULF COAST...BUT SOME ISOLATED STORMS ON THE NORTHERN
FRINGES OF THE COMPLEX COULD STILL BECOME SEVERE. THE ACTIVITY
SHOULD BE MOSTLY EAST OF CENTRAL ALABAMA BY 6 PM THIS EVENING...
AND JUST LEFT SMALL RAIN CHANCES IN FOR THE EASTERN COUNTIES
THROUGH 9 PM TO HANDLE ANY LINGERING STORMS. A SURFACE LOW WILL
PASS TO THE NORTHEAST OF ALABAMA LATER TONIGHT AND A COLD FRONT
WILL PUSH INTO NORTH ALABAMA ON SUNDAY. THE AIR MASS WILL BE
MOISTURE STARVED FOR ANY CONVECTION ALONG FRONT ON SUNDAY. THE
FRONT WILL BRING SOME COOLER AND DRIER AIR INTO ALL OF CENTRAL
ALABAMA SUNDAY NIGHT AND MONDAY. SOME OF THE NORTHERN COUNTIES
WILL LIKELY SEE LOWS IN THE MIDDLE TO UPPER 40S TUESDAY MORNING.

A DEEP UPPER LOW OVER THE SOUTHERN ROCKIES WILL SLOWLY SHIFT EASTWARD
ON MONDAY. THE UPPER LOW WILL BE HELD BACK BY THE PRESENCE OF AN
UPPER TROF OVER THE ATLANTIC SEABOARD. THE EASTERN TROF WILL FINALLY
MOVE INTO THE ATLANTIC BY TUESDAY AND THE PLAINS SYSTEM WILL PULL
SOME GULF MOISTURE NORTHWARD INTO THE LOWER MISSISSIPPI RIVER
VALLEY. SHOWERS WILL SPREAD INTO ALABAMA ON TUESDAY FROM THE
SOUTHWEST AND LIKELY OVERSPREAD ALL OF CENTRAL ALABAMA TUESDAY
NIGHT. AS THE UPPER TROF APPROACHES ALABAMA THE SURFACE FLOW
STAYS MAINLY OUT OF THE EAST...AND INSTABILITY SHOULD BE RATHER
LIMITED. THE GFS AND ECMWF MODELS DIVERGE IN THEIR SOLUTIONS WITH
THIS SYSTEM BEYOND TUESDAY. THE ECMWF MODEL IS MORE PROGRESSIVE
WITH THE UPPER TROF AND MOVES THE SYSTEM EAST OF ALABAMA WEDNESDAY
NIGHT... WHILE THE GFS ELONGATES THE TROF AND HANGS IT UP OVER THE
GULF COAST STATES. THE CANADIAN AND DGEX MODELS SHOW A MORE
PROGRESSIVE SOLUTION AND FAVORED THIS SCENARIO.
