DISCUSSION
KEY MESSAGE 1) FOG REDEVELOPMENT OVERNIGHT.
SURFACE RIDGE OFF TO THE SOUTHEAST WITH A LIGHT SOUTHERLY FLOW
OVERNIGHT. WITH ABUNDANT LOW LEVEL MOISTURE, LIGHT WIND FLOW, AND
ONLY SOME HIGH LEVEL CLOUDS - FOG AND STRATUS REDEVELOPS AND EXPANDS
OVERNIGHT. LATEST IR SATELLITE IMAGERY AND OBSERVATIONS SHOWING FOG
AND STRATUS DEVELOPING ACROSS THE CENTER OF ILN/S FA - GENERALLY ALONG
THE I-71 CORRIDOR. GUIDANCE CONTINUES TO SHOW A FAVORABLE SIGNAL FOR
THIS FOG/STRATUS TO EXPAND. HREF SHOWS >70 PERCENT PROBABILITY OF
<1/4 MILE VISIBILITY GENERALLY NORTH OF THE OHIO RIVER.
HAVE ISSUED A DENSE FOG ADVISORY FOR AREAS NORTH OF THE OHIO RIVER
OVERNIGHT INTO TUESDAY MORNING. THE DENSE FOG WILL IMPACT THE
TUESDAY MORNING COMMUTE. FOG IS NOT EXPECTED TO LINGER QUITE AS LONG
AS THIS MORNING WITH INCREASED RETURN FLOW THAT WILL HELP BREAK THE
DECOUPLED LAYER AND ENHANCE MIXING. HAVE THE DENSE FOG ADVISORY IN
EFFECT UNTIL 10 AM.
WILL CONTINUE TO MONITOR AREAS SOUTH OF THE RIVER BUT MORE CLOUDS
MAY PREVENT WIDESPREAD DENSE FOG FROM DEVELOPING ACROSS THE SOUTH.
KEY MESSAGE 2) TEMPERATURES RISING MUCH ABOVE NORMAL.
MODELS REMAIN CONSISTENT IN DEVELOPMENT OF AN H5 RIDGE THAT EXPANDS
ACROSS THE OHIO VALLEY. THIS WILL RESULT IN A GRADUAL WARMING TREND
THROUGH THE WORK WEEK, WITH WEDNESDAY AND THURSDAY REMAINING THE
WARMEST DAYS OF THE PERIOD. SOME UNCERTAINTY ON HOW WARM IT WILL GET
DURING THE DAYTIME WITH INCREASING CHANCES FOR PCPN AND RESIDUAL
CLOUD COVER, BUT NONETHELESS, TEMPERATURES WILL TREND WELL ABOVE
SEASONAL NORMALS.
KEY MESSAGE 3) CHANCE FOR SHOWERS/STORMS AND INCREASED WINDS MID TO
LATE WEEK.
THE H5 RIDGE FLATTENS DURING THE MIDDLE OF THE WEEK, WHICH WILL HELP
RESULT IN A MORE ACTIVE PATTERN THE NEXT FEW DAYS. ILN WILL BE FIRMLY
PLANTED IN THE WARM SECTOR OF A SURFACE LOW THAT WILL BE SITUATED
ACROSS THE NORTHERN PLANS ON WEDNESDAY. WITH CONTINUED SOUTHWESTERLY
FLOW USHERING IN A WARM AND RELATIVELY HUMID AIR MASS, RAIN SHOWERS
ARE EXPECTED TO DEVELOP DURING THE DAY. CANNOT RULE OUT A FEW RUMBLES
OF THUNDER WITH MARGINAL INSTABILITY. ADDITIONALLY, BREEZY CONDITIONS
DEVELOP DURING THE DAYTIME, WITH SUSTAINED WINDS AROUND 15-20 MPH AND
GUSTS UP TO 35 MPH.
SPC HAS INTRODUCED A DAY 4 OUTLOOK FOR POTENTIAL SEVERE WEATHER THAT
ENCOMPASSES PORTIONS OF THE TRISTATE INTO SOUTHWEST OH. THIS IS IN
RESPONSE TO THE ADVANCING SURFACE LOW THAT WILL MOVE THROUGH THE
MIDWEST REGION THURSDAY NIGHT INTO FRIDAY. THE TIMING FOR SEVERE
POTENTIAL HERE APPEARS TO BE LATE DAY THURSDAY INTO THURSDAY NIGHT
BASED ON THE PROGRESSION OF THE LOW. SOME INSTABILITY WILL BE
AVAILABLE, BUT THIS STILL APPEARS TO BE MARGINAL AT BEST (WITH
OVERNIGHT TIMING BEING LESS IDEAL). HOWEVER, FAVORABLE KINEMATICS
WILL BE IN PLACE GIVEN THE STRONG WIND SHEAR PROFILES. WHILE NOT A
SLAM DUNK SEVERE SCENARIO, WILL NEED TO MONITOR TRENDS WITH THIS
SYSTEM FOR POTENTIAL IMPACTS.
COLD FRONT MOVES THROUGH FRIDAY, USHERING IN A COLDER AIR MASS ONCE
AGAIN AND WILL REDUCE PCPN CHANCES LATER IN THE DAY. BREEZY
CONDITIONS DEVELOP ONCE AGAIN ON FRIDAY, WITH GUSTS OF 25-30 MPH
POSSIBLE. IT SHOULD BE NOTED THAT WE MAY OBSERVE SOME SNOW
DEVELOPING ACROSS OUR NORTH THIS WEEKEND, BUT WILL HAVE TO MONITOR
TRENDS BEFORE GETTING INTO TOO MANY DETAILS.
AVIATION /02Z TUESDAY THROUGH SATURDAY/
