..NO SVR TSTM AREAS FORECAST...

WSWLY ZONAL FLOW ALOFT ACROSS THE CONUS WILL CONTINUE TONIGHT AS AN
UPPER-LEVEL TROUGH APPROACHES THE WEST COAST. THE EXIT REGION OF A
90 TO 100 KT MID-LEVEL JET IS FORECAST TO MOVE INLAND ACROSS FAR NRN
CA. NORTH OF THIS FEATURE...FORECAST SOUNDINGS TONIGHT SHOW STEEP
MID-LEVEL LAPSE RATES ACROSS ORE AND WA. THIS COMBINED WITH COLD AIR
ALOFT AND STRONG LARGE-SCALE ASCENT AHEAD OF THE TROUGH AXIS MAY
SUPPORT ISOLATED THUNDERSTORM DEVELOPMENT ALONG THE COAST OF WA AND
NW ORE. OTHERWISE...THUNDERSTORM ACTIVITY IS NOT EXPECTED ACROSS THE
CONUS TONIGHT.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0215 PM CDT TUE MAR 25 2008

VALID 252000Z - 261200Z

..NO SVR TSTM AREAS FORECAST...

..PACIFIC NW...

A STRONG UPPER JET WILL ADVANCE INTO NRN CA AND SWRN OR. COLD AIR
ALOFT WITH -36C AT 500 MB ON CYCLONIC SIDE OF THE UPPER JET WILL
MAINTAIN STEEP LAPSE RATES AND MARGINAL INSTABILITY...ESPECIALLY
ALONG COASTAL REGIONS OF THE PACIFIC NW. SCATTERED CONVECTION
PERSISTS WITHIN THIS ENVIRONMENT...AND A FEW LIGHTNING STRIKES HAVE
BEEN OBSERVED OFFSHORE. ISOLATED THUNDERSTORMS WILL REMAIN POSSIBLE
MAINLY NEAR COASTAL WA AND OR WHERE SLIGHTLY GREATER INSTABILITY
EXISTS.

..MID MS VALLEY REGION...

MODIFIED CP AIR IS RETURNING NWD BENEATH STEEPER LAPSE RATES
ASSOCIATED WITH EWD ADVECTING EML. THIS WILL RESULT IN MARGINAL
INSTABILITY TONIGHT OVER PARTS OF THE SRN AND CNTRL PLAINS INTO THE
MID MS VALLEY. CURRENT INDICATIONS ARE THAT THE EML WILL REMAIN TOO
WARM RELATIVE TO THE DEGREE MOISTURE RETURN...AND CONTRIBUTE TO A
CAP. MODELS ARE IN AGREEMENT THAT CONVECTION WILL DEVELOP ON NOSE OF
SWLY LOW LEVEL JET IN VICINITY OF BAROCLINIC ZONE ACROSS SRN MO
LATER TONIGHT. SOME OF THIS ACTIVITY COULD BECOME DEEP ENOUGH TO
PRODUCE LIGHTNING WHERE THE CAP MAY BE WEAKER NEAR ERN FRINGE OF EML
FROM SERN MO INTO WRN KY. MOST CONVECTION WILL LIKELY REMAIN SHALLOW
BELOW A 700 MB INVERSION...SO COVERAGE OF THUNDERSTORMS WILL
PROBABLY BE LESS THAN 10%.

..DISCUSSION...
PROGRESSIVE AND NEARLY ZONAL MID-UPPER LEVEL PATTERN WILL DOMINATE
MUCH OF CONUS...PERTURBED PRIMARILY ACROSS NRN STATES BY SHORTWAVE
TROUGHS NOW OVER SRN GULF OF AK AND BERING SEA. LEAD TROUGH SHOULD
MOVE EWD FROM VICINITY UPPER MS VALLEY ACROSS GREAT LAKES AND NEW
ENGLAND DAYS 4-5/28TH-30TH. TIMING/TRACK UNCERTAINTIES IN VARIOUS
DETERMINISTIC AND ENSEMBLE PROGS -- DISCUSSED IN MORE DETAIL IN
DAY-3 OUTLOOK -- ALSO AFFECT ASSOCIATED SFC RESPONSES DAY
4-5...PRIMARILY REGARDING TRAILING SEGMENT OF SFC FRONTAL ZONE
ACROSS SRN PLAINS. STG LEE-SIDE PRESSURE FALLS ARE LIKELY AHEAD OF
NEXT MAJOR SHORTWAVE -- PROGGED BY ECMWF...GFS AND SEVERAL MREF
MEMBERS OVER MT OR SRN AB DAY-5/29TH-30TH. HOWEVER...CONSIDERABLE
DOUBT EXISTS ON JUXTAPOSITION OF FAVORABLE RETURN FLOW MOISTURE
BEHIND PRIOR FROPA WITH OPTIMAL MID/UPPER WIND PROFILES...IN SUPPORT
OF ANY POTENTIAL SVR EVENT IN CENTRAL/SRN HIGH PLAINS. AFTER
DAY-5...THERE IS TOO MUCH DIVERSITY IN SHORTWAVE PROGS AND THEIR LOW
LEVEL RESPONSES TO JUSTIFY CATEGORICAL SVR AREA.

VALID 271200Z - 281200Z

..THERE IS A SLGT RISK OF SVR TSTMS PORTIONS SRN/ERN OK...EXTREME
N-CENTRAL TX...WRN AR...

..SYNOPSIS...
MID/UPPER LEVEL SHORTWAVE TROUGH -- NOW EVIDENT IN MOISTURE CHANNEL
IMAGERY IN SRN RIM OF GULF OF AK VORTEX...IS EXPECTED TO TURN EWD
ACROSS PACIFIC NW AND NRN ROCKIES DAY-2...THEN EWD ACROSS N-CENTRAL
PLAINS AND UPPER MS VALLEY THIS PERIOD. OPERATIONAL SPECTRAL AND A
COUPLE SPECTRAL/WRF SREF MEMBERS REPRESENT SLOWEST OUTLIERS AND
ALREADY APPEAR TOO SLOW BASED ON CURRENT SATELLITE TRENDS.
MEANWHILE OPERATIONAL NAM IS FAST OUTLIER...WITH SREF CONSENSUS PROG
OF PERTURBATION PREFERRED ATTM.

SFC COLD FRONT SHOULD MOVE SWD ACROSS CENTRAL AND PERHAPS PORTIONS
SRN PLAINS IN WAKE OF EJECTING FRONTAL/WAVE LOW...DECELERATING AT
LEAST TEMPORARILY DURING MIDDLE PART OF PERIOD AS PRESSURE FALLS
OCCUR OVER SRN/CENTRAL HIGH PLAINS. STRENGTH/POSITION OF SUCH
FALLS...AND OTHER ASPECTS OF BOUNDARY LAYER MASS FIELDS...VARY
CONSIDERABLY IN NUMERICAL GUIDANCE BUT ARE ABSOLUTELY CRITICAL TO
PLACEMENT/MAGNITUDE OF SVR POTENTIAL THIS PERIOD. BY
28/00Z...VARIOUS OPERATIONAL/SREF SOLUTIONS INDICATE CONSIDERABLE
DIVERSITY OF FRONTAL POSITIONS -- ANYWHERE FROM S-CENTRAL KS TO I-20
AREA IN N-CENTRAL TX. GIVEN TENDENCY OF MANY PROGS TO UNDER-FCST
LATE WINTER/EARLY SPRING SFC FRONTAL SURGES...FCST FOR LATE
AFTERNOON IS WEIGHTED TOWARD SRN PORTION OF ENSEMBLE
CONSENSUS...WHICH WOULD BE SWRN/S-CENTRAL OK NEWD ACROSS OZARKS TO
FRONTAL-WAVE LOW OVER IL/INDIANA. EXPECT CONTINUED GULF AIR MASS
MODIFICATION AND ADVECTION OF RESULTANT MOISTURE NWD/NEWD OVER SRN
PLAINS...OZARKS AND LOWER OH VALLEY. AS THIS OCCURS...DRYLINE
SHOULD BECOME INCREASINGLY WELL DEFINED THROUGH PERIOD...FROM
S-CENTRAL TX NNEWD TO FRONTAL INTERSECTION OVER SRN OK.

..OH VALLEY TO SRN PLAINS...
WIDELY SCATTERED TO SCATTERED TSTMS MAY DEVELOP INVOF FRONT DURING
AFTERNOON...AS FAR SW AS DRYLINE INTERSECTION. NERN PORTION OF THIS
CORRIDOR WOULD TREND MORE TOWARD WIND THREAT...WITH LARGE HAIL MORE
PROBABLE OVER RED RIVER REGION. ACTIVITY SHOULD BE SUPPORTED BY
INFLOW LAYER EMANATING FROM NARROW PLUME OF WARM-SECTOR MOISTURE
RETURN...COMBINED WITH FRONTAL ASCENT AND DIABATIC/DIURNAL HEATING.
STRONGER CAPPING IS EXPECTED WITH SWWD EXTENT DOWN FRONTAL
ZONE...RELATED TO ELEVATED MIXED LAYER. HOWEVER...ALSO EXPECT
STEEPER LAPSE RATES ALOFT...MORE MOISTURE...STRONGER HEATING AND
LARGER BUOYANCY ACROSS OK/N TX PORTION OF OUTLOOK AREA THAN FARTHER
NE...LEADING TO CONDITIONAL/SIGNIFICANT SVR POTENTIAL. GIVEN
STRENGTH/PERSISTENCE OF ANTECEDENT EML...DRYLINE PROBABLY WILL
REMAIN TOO CAPPED TO SUPPORT MORE THAN VERY ISOLATED CONVECTIVE
THREAT.

VERTICAL SHEAR PROFILES WILL BE FAVORABLE ALONG MOST OF FRONTAL
ZONE...WITH ACTUAL SVR THREAT STRONGLY DICTATED BY MESOSCALE AND
SMALLER INFLUENCES ON CONVECTIVE MODE. GIVEN AFOREMENTIONED SPATIAL
AND MODAL UNCERTAINTIES...UNCONDITIONAL SVR PROBABILITIES ARE KEPT
AT MRGL THRESHOLDS FOR CATEGORICAL SLGT RISK OVER SRN PLAINS...AND
JUST BELOW THAT FARTHER NE.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1209 AM CDT TUE MAR 25 2008

VALID 261200Z - 271200Z

..NO SVR TSTM AREAS FORECAST...

..SYNOPSIS...
MOISTURE CHANNEL IMAGERY INDICATES PERSISTENT CYCLONIC GYRE OVER
GULF OF AK...ALONG WITH SHORTWAVE TROUGH IN ITS SWRN SEMICIRCLE THAT
WILL COME ASHORE PACIFIC NW EARLY IN DAY-2 PERIOD. THIS TROUGH
SHOULD MOVE ESEWD TO NEB/SD BY 27/12Z...FOLLOWED BY SERIES OF
UPSTREAM/PERTURBATIONS LARGELY TRAVELING ALONG AND N OF 130-145 KT
250 MB JET CORE. ASSOCIATED STEEP MIDLEVEL LAPSE RATES IN COLD AIR
ALOFT -- BENEATH LEFT EXIT REGION OF CYCLONICALLY CURVED UPPER JET
MAX -- MAY SUPPORT ISOLATED TSTMS WITHIN BROAD SWATH OF NWRN CONUS.
AT SFC...LEE CYCLONE SHOULD DEVELOP BY 27/00Z OVER NERN CO/SWRN NEB
AREA...WITH WARM FRONT BECOMING MORE SHARPLY DEFINED ESEWD ACROSS
KS/MO.

..CENTRAL/SRN PLAINS...
CONDITIONAL POTENTIAL FOR SUPERCELLS IS EVIDENT OVER PORTIONS SRN
PLAINS E OF DEVELOPING DRYLINE...GIVEN LIKELY OVERLAP OF BROADLY
CURVED HODOGRAPHS AND FAVORABLE DEEP-LAYER SHEAR PROFILES WITH
INCREASING LOW LEVEL MOISTURE. ATTM...IT APPEARS THAT MLCINH IN
BASE OF ELEVATED MIXED LAYER WILL REMAIN TOO STRONG...WITH LOW LEVEL
LIFT TOO WEAK...TO SUPPORT CONVECTIVE INITIATION IN THIS
ENVIRONMENT...DESPITE SOME NEARLY UNCAPPED NAM FCST SOUNDINGS.

STRONGEST LOW LEVEL CONVERGENCE/ASCENT WILL BE INVOF SFC LOW OVER
CENTRAL HIGH PLAINS...AS WELL AS SRN PERIPHERY OF MIDLEVEL DPVA IN
ADVANCE OF SHORTWAVE TROUGH. HOWEVER...THIS AREA ALSO WILL BE
DISPLACED FROM SIGNIFICANT LOW LEVEL MOISTURE. LATEST OPERATIONAL
NAM-WRF MAY BE TOO AGGRESSIVE WITH BOUNDARY LAYER MOIST ADVECTION
ACROSS MUCH OF CENTRAL/SRN PLAINS...GIVEN ITS OWN HISTORY WITH
EARLY-STAGE RETURN FLOW EVENTS...AND GIVEN CURRENT STATE OF GULF AIR
MASS MODIFICATION WITH SUBSTANTIAL 925-850 MB OFFSHORE FLOW STILL
EVIDENT OVER MUCH OF GULF COAST.

THEREFORE...EXPECT MINIMAL DEEP CONVECTION BEFORE DARK...WITH
POSSIBLE EXCEPTION OF VERY HIGH BASED ACTIVITY INVOF SFC LOW. SOME
POTENTIAL EXISTS FOR THIS ACTIVITY TO PRODUCE STG SFC GUSTS GIVEN
DEEP/DRY SUBCLOUD LAYERS AND STRENGTH OF AMBIENT FLOW IN
CLOUD-BEARING LAYER. HOWEVER...SVR POTENTIAL APPEARS TOO ISOLATED
AND UNCERTAIN TO WARRANT UNCONDITIONAL PROBABILITIES ATTM.
CONVECTION MAY PERSIST THROUGH EVENING/OVERNIGHT HOURS AS ASSOCIATED
REGIME OF ELEVATED/LOW-LEVEL ASCENT SHIFTS EWD ACROSS CENTRAL PLAINS
INTO PROGRESSIVELY LESS MOISTURE-DEFICIENT ENVIRONMENT. TOWARD END
OF PERIOD...THIS ACTIVITY MAY MOVE FAR ENOUGH E ACROSS CENTRAL
PLAINS AND CORN BELT TO AFFECT WRN PORTION OF AREAS PREVIOUSLY
COVERED BY SEPARATE CONVECTIVE REGIME DISCUSSED BELOW.

..OZARKS TO LOWER MO/OH RIVER VALLEY REGIONS...
LLJ -- ALREADY EVIDENT ATTM FROM SWRN/S-CENTRAL TX ACROSS CENTRAL K
AND OZARKS -- WILL UNDERGO CHARACTERISTIC DIURNAL/NOCTURNAL
OSCILLATIONS RELATED TO BOUNDARY LAYER DECOUPLING THROUGH PERIOD.
DURING DAY-2...SUFFICIENT AIR MASS MODIFICATION SHOULD OCCUR OVER
WRN GULF FOR NARROW PLUME OF MOISTURE TO ADVECT NEWD ACROSS THIS
REGION. ACCOMPANYING MOISTENING AMIDST LOW LEVEL WAA WILL SUPPORT
INCREASING TSTM POTENTIAL THROUGH MID-LATE EVENING HOURS OVER
MO/IL...SPREADING/MOVING ENEWD OVERNIGHT. TIME SERIES OF FCST
SOUNDINGS REASONABLY SUGGESTS BUOYANCY -- AND LIKEWISE THUNDER
POTENTIAL -- SHOULD BECOME WEAKER AND MORE ELEVATED WITH EWD EXTENT
ACROSS THIS SWATH OVERNIGHT AS LEADING PORTION OF STRONGEST WAA AND
MOISTENING GRADUALLY BECOMES MORE DIFFUSE. ERN EDGE OF TSTM
POTENTIAL THEREFORE IS MORE ILL-DEFINED THAN ANY CATEGORICAL LINE
CAN INDICATE.
