HIGHLY AMPLIFIED PATTERN OVER COUNTRY THIS PERIOD WITH UPPER TROF
OVER THE GREAT LAKES AND RIDGE OVER THE WEST. HAVE FOLLOWED NAM
IN SHORT TERM AS IT VERIFIED WELL AT 6Z. SURFACE LOW OVER OHIO TO
CONTINUE TO DEEPEN AS IT MOVES INTO NEW YORK LATER TODAY. STRONG
GRADIENT BETWEEN LOW AND HIGH DROPPING SOUTH THROUGH THE PLAINS TO
BRING BLUSTERY CONDITIONS TO THE AREA THROUGH TONIGHT. CLOUDS
CONTINUE TO ROTATE AROUND LOW OVER STATE HOLDING TEMPERATURES UP
EARLY THIS MORNING. PARTIAL CLEARING THIS MORNING AS DRIER AIR
MOVES IN...BEFORE SHORT WAVE NORTH OF LAKE SUPERIOR MOVES THROUGH
THIS AFTERNOON AND EVENING. WILL STAY WITH PREVIOUS FORECAST
THOUGHTS OF ONLY FLURRIES/ISOLATED LIGHT SNOW SHOWERS FOR THIS
AFTERNOON WITH CONTINUED CYCLONIC FLOW AND STEEP LLVL LAPSE RATES. FOR
TONIGHT...NAM SUGGESTS CLOUDS CURRENTLY SHIFTING SOUTH THROUGH
ONTARIO TO AFFECT AREA. HAVE BUMPED TEMPS UP A BIT GIVEN EXPECTED
CLOUD COVER.

RIDGE BUILDS IN FOR TUESDAY. TEMPERATURES TO SLOWLY RECOVER...
THOUGH REMAIN BELOW SEASONAL NORMS.

.LONG TERM...TUE NGT THRU NXT SUNDAY. SPLIT FLOW WL CONT THRU THE
END OF THE WEEK WITH THE MORE ACTIVE SRN BRANCH BRINGING TWO UPR
LOWS INTO THE CONUS. SPD DIFFERENCES REMAIN THE BIGGEST HURDLE
AMONG THE MDLS AS THE FIRST UPR LOW PASSES WELL TO OUR SOUTH
THU/FRI. THE SECOND UPR LOW MAY ALSO STAY TO OUR SOUTH...BUT NOT
AFFECT NE WI TIL EARLY NXT WEEK. TEMPS EXPECTED TO BE NEAR NORMAL
THRU NXT WEEKEND.

NW FLOW TO PERSIST OVR THE WRN GREAT LKS TUE NGT WITH THE MDLS
INDICATING A WEAK SFC TROF SLIDING SEWD INTO AT LEAST THE WRN
THIRD OF WI BY 12Z WED. THERE IS ALSO A RATHER STG SHRTWV WHICH
THE MDLS MOV INTO THE NRN PLAINS DURING THE NGT. WHILE NO PCPN IS
EXPECTED...ANTICIPATE AT LEAST AN INCREASE IN MID/HI CLDS AND HAVE
INCREASED CLD CVR THROUGHOUT NE WI. DUE TO MORE CLDS IN THE VCNTY...
HAVE ADDED A COUPLE OF DEGS TO THE MIN TEMPS FROM THE PREV FCST.

THE SHRTWV RACES SE INTO NRN IL ON WED AS THE SFC TROF COMPLETES
ITS TREK ACROSS WI. MSTR AVAILABILITY APRS TO BE AN ISSUE AS FCST
SNDNGS INDICATE THAT THE LOW LVLS OF THE ATM DO NOT SATURATE.
WHILE A FEW SPRINKLES ARE PSBL...NOT ENUF COVERAGE TO MENTION IN
THE FCST...THUS A DRY FCST LEFT ALONE. GUID MAY BE TOO OPTIMISTIC
WITH TEMPS CONSIDERING A DECENT DOSE OF MID/HI CLDS OVRHD. PREFER
THE COOLER MAV GUID AS A STARTING POINT...BUT EVEN KNOCKED A FEW
DEGS OFF OF THOSE VALUES.

ATTN SHIFTS BACK TO THE ROCKIES WED NGT WHERE THE FIRST UPR LOW TO
BE MOVG EAST DUE TO AN UPSTREAM KICKER HEADED TOWARD THE PACIFIC
NW. GFS ALREADY AHD OF THE OTHER MDLS AND BASED ON ITS PERFORMANCE
OVR THE PAST SEVERAL WEEKS (TOO FAST/TOO STG)...PREFER TO USE THE
SLOWER SPD OF THE ECMWF/UKMET/CANADIAN. A QUIET NGT FOR NE WI
UNDER MOSTLY CLR TO PARTLY CLDY SKIES AND TEMPS JUST A BIT BLO
NORMAL (20S TO AROUND 30). AS THE UPR LOW ENTERS THE CNTRL/SRN
PLAINS ON THU...A STRENGTHENING SFC LOW IS FCST TO RESIDE OVR
EITHER SRN KS OR NRN OK. INCREASING SOUTHERLY WNDS AHD OF THIS
SYSTEM WL BEGIN TO TAP GULF MSTR AND TRANSPORT THE MSTR TOWARD THE
MO VALLEY RGN BY 00Z FRI. NE WI TO BE PROTECTED BY AN AREA OF HI
PRES...THUS A DECENT AMT OF SUNSHINE EXPECTED WITH TEMPS PERHAPS A
DEG OR TWO WARMER THAN WED.

THE SYSTEM IS PROGGED TO MOV ALMOST DUE EAST TOWARD THE TN VALLEY
BY FRI AND WITH HI PRES ESSENTIALLY ANCHORED FROM ONTARIO TO NRN
SECTIONS OF THE GREAT LKS...IT APRS THAT NE WI WL NOT BE AFFECTED
WITH ANY PCPN. OTHER THAN MORE SUN NORTH/MORE CLDS SOUTH...THE
TRANQUIL WEATHER TO CONT ACROSS THE FCST AREA. AS THIS SYSTEM
HEADS TOWARD THE MID-ATLANTIC STATES ON SAT...HI PRES TO REMAIN
THE DOMINANT FORCE OVR NE WI. ONLY PBLM COULD BE THE EASTERLY WNDS
WHICH WOULD KEEP TEMPS IN CHECK...ESP FOR THE LKSHR COUNTIES WHERE
READINGS WL BE STUCK IN THE MID 40S FOR MAX TEMPS ON SAT.

THE SECOND UPR LOW IS EXPECTED TO BE PUSHING ACROSS THE ROCKIES
AND INTO THE CNTRL PLAINS NXT SUNDAY. TOO EARLY TO TELL WHAT
IMPACT THIS SYSTEM WL EVENTUALLY HAVE FOR NE WI AND IT WOULD NOT
BE UNTIL MON AT THE EARLIEST (IF AT ALL). SUNDAY LOOKS NICE WITH
WARMING TEMPS FOR ALL EXCEPT RIGHT ALONG THE BAY AND LAKE.
