DISCUSSION
KEY MESSAGE 1...BELOW NORMAL TEMPERATURES ARE EXPECTED THROUGH
FRIDAY.
SKIES REMAIN CLOUDY ACROSS MUCH OF THE FORECAST AREA THIS
EVENING. LOW TEMPS WILL DROP BACK INTO THE 40S TO NEAR 50
TONIGHT, WITH 30S POSSIBLE IN THE HIGHER ELEVATIONS. THERE
SHOULD BE ENOUGH LINGERING WIND TO PRECLUDE FROST CONCERNS, BUT
IT COULD BE CLOSE IN SOME OF THE ELEVATED SHELTERED VALLEYS.
AN UPPER LOW WILL PUSH OFFSHORE ON FRI, WHICH WILL LEAD TO
WARMER TEMPS. EVEN SO, READINGS WILL LIKELY FALL A FEW DEGREES
SHORT OF NORMAL. WHILE THERE SHOULD BE MORE BREAKS OF SUN
COMPARED TO THU, MID AND HIGH LEVEL CLOUDS MAY INCREASE IN THE
AFTERNOON. NW'LY WINDS WILL STILL BE A BIT GUSTY, BUT SHOULD
START DIMINISHING DURING THE AFTERNOON AS SURFACE HIGH PRESSURE
BUILDS SOUTH OF THE AREA.
KEY MESSAGE 2...ABOVE AVERAGE TEMPERATURES ARE EXPECTED BEGINNING THIS
WEEKEND ALONG WITH DAILY SHOWER AND THUNDERSTORM CHANCES THROUGH
THE MIDDLE OF NEXT WEEK.
SFC HIGH WILL MOVE OFFSHORE OVER THE WEEKEND. THE COMBINATION
OF RETURN FLOW AND RISING HEIGHTS WILL LEAD TO TEMPS RISING
ABOVE NORMAL, WITH SOME LOCATIONS POTENTIALLY NEARING 90 BY
SUN. THE ONE CAVEAT IS THE UPPER LEVEL PATTERN WILL STILL BE
RELATIVELY ZONAL, AND A COLD FRONT WILL ATTEMPT TO DROP SOUTH
FROM THE GREAT LAKES. EMBEDDED SW TROFS IN THIS FLOW COULD HELP
INITIATE SOME DIURNAL CONVECTION EACH DAY ALONG WITH TERRAIN
CIRCULATIONS. COVERAGE DOES APPEAR LIMITED, HOWEVER. THE
SAGGING FRONT WILL LIKELY QUICKLY RETURN NORTH AS UPPER LEVEL
RIDGING STARTS BUILDING SUN NIGHT.
UPPER LEVEL RIDGING AND RETURN FLOW FROM THE SOUTH WILL CAUSE
TEMPS TO CONTINUE TO WARM INTO THE START OF NEXT WEEK, WITH
HIGHS POTENTIALLY INTO THE 90S MONDAY AND TUESDAY. WHILE SFC
HIGH PRESSURE IS EXPECTED TO PERSIST OFFSHORE, INCREASING
DIURNAL INSTABILITY COULD LEAD TO DAILY CONVECTION DEVELOPING
OVER THE HIGHER TERRAIN.
OFF TO THE WEST, A DEEP TROF BEGINS TO DEVELOP OVER THE
NORTHERN PLAINS, WITH A COLD FRONT THAT WILL SLOWLY BEGIN TO
APPROACH THE REGION BETWEEN TUE AND WED. THIS WILL BRING MORE
WIDESPREAD CHANCES FOR RAIN AND THUNDERSTORMS, ALTHOUGH
TEMPS MAY NOT BEGIN TO SEE A SIGNIFICANT DECREASE UNTIL AFTER
IT TRANSITIONS OFFSHORE SOMETIME MID-TO-LATE NEXT WEEK.
AVIATION /01Z FRIDAY THROUGH TUESDAY/
NW WIND GUSTS REMAIN 20-25 KTS THRU THIS EVE WITH CONTINUED
VFR. WINDS SHOULD DECREASE A BIT TONIGHT, ALTHOUGH SOME
OCCASIONAL GUSTS WILL LIKELY PERSIST THROUGH THE NIGHT (EXCEPT
CHO). CIGS SHOULD SCATTER OUT AS WELL, BUT IT'S A BIT UNCERTAIN
HOW QUICKLY THAT OCCURS.
GUSTY NW WINDS FRI WITH GUSTS AROUND 20 KTS, PERHAPS A BIT
LIGHTER THAN TODAY, AND THEY WILL DIMINISH IN THE AFTERNOON AS
HIGH PRESSURE APPROACHES.
VFR CONDITIONS ARE LIKELY SAT WITH LIGHT S/SW WINDS. A SHOWER
OR TSTORM COULD APPROACH MRB DURING THE EVENING.
PRIMARILY VFR CONDITIONS ARE EXPECTED AT TERMINALS ON SUN AND

TERMINALS. WINDS BRIEFLY SHIFT W'LY BY SUN AFTERNOON BEFORE
SHIFTING SSE ON MON.

A FEW KTS. THE SCA ENDS AT 3 PM, ALTHOUGH THERE IS SOME
UNCERTAINTY WITH HOW QUICKLY WINDS DECREASE. LIGHT WINDS ARE
EXPECTED BY FRI EVENING AS HIGH PRESSURE BUILDS TO THE S.
