ALONG AND BEHIND THE TROF AXIS EXPECT AN INCREASING WESTERLY FLOW ALOFT WITH INCREASING SUBSIDENCE IN ITS WAKE. EXPECT RIDGE TOP AND EAST SLOPE WINDS SPEEDS TO INCREASE DURING THE EARLY MORNING HOURS UP TO 45 MPH OR SO. THE UPPER TROF WILL STILL BE SLOWLY MOVING OVER THE FAR PLAINS THIS AFTERNOON WITH SOME LIFT. IT WILL BE HOTTER ON WEDNESDAY WITH A RIDGE OF HIGH PRESSURE OVER COLORADO.
147 PM EDT TUE JUL 7 2015 AN UPPER LEVEL TROUGH WILL MOVE EAST OF THE AREA THIS AFTERNOON.

DRAGGED IN WITH NORTHERLY SURFACE FLOW/SUBSIDENCE BEHIND DEPARTING COLD FRONT. SKIES WERE SLOWLY CLEARING FROM NORTHWEST TO SOUTHEAST BEHIND THE DEPARTING COLD FRONT WHILE TEMPERATURES AT 2 AM HOVERED IN THE MIDDLE 50S ACROSS NORTHERN WI. LOOK FOR COOLER/DRIER CONDITIONS TODAY AS HIGH PRESSURE BUILDS IN FROM THE NORTHERN PLAINS INTO THE UPPER MISSISSIPPI RIVER REGION.

THROUGH TONIGHT THE COLD FRONT IS CURRENTLY COMPLETING ITS PASSAGE ACROSS SE MI. EXPANSIVE HIGH PRESSURE CURRENTLY OVER THE NORTHERN PLAINS WILL TAKE OVER DURING THE DAY ON WEDNESDAY AS IT MOVES EAST INTO THE GREAT LAKES REGION. THIS HIGH WILL BRING A DAY OF DRIER CONDITIONS BEFORE THE NEXT LOW ENTERS BACK INTO THE PICTURE. LOW PRESSURE WILL BE IN THE PROCESS OF MOVING IN FROM THE SOUTHWEST LATE WEDNESDAY NIGHT BRINGING ANOTHER CHANCE FOR RAIN. ESPECIALLY AREAS CLOSER TO THE OHIO BORDER AS THE LOW SKIRTS ALONG NORTHERN OHIO AND LAKE ERIE.
A COLD FRONT CURRENTLY OVER THE EASTERN PLAINS WILL CONTINUE TO MOVE TOWARDS THE REGION TODAY BUT WILL STALL BEFORE IT REACHES OUR CWA.

WITH BULK OF RAIN CONTAINED TO THE RIDGES BY THE AFTERNOON. WITH THE LOW OFF TO THE EAST.
THE PERSISTENT RIDGE OF HIGH PRESSURE RESPONSIBLE FOR THE EARLY JULY HEAT WAVE WILL GRADUALLY WEAKEN THIS WEEK AS ONSHORE FLOW STRENGTHENS A BIT. AN UPPER LOW OFF CALIFORNIA MAY DRIFT FAR ENOUGH NORTH THIS WEEK TO BRING THUNDERSTORMS TO THE CASCADE CREST IN LANE COUNTY WED AFTERNOON. TEMPERATURES WILL COOL DOWN CLOSER TO SEASONAL NORMALS BY THE END OF THE WEEK AS A TROUGH OF LOW PRES APPROACHES THE COAST.

/61 AT BMX/ HIGH PRESSURE RIDGE IN PLACE WITH CENTER OF RIDGE TO THE EAST OF ALABAMA AND WEAK SOUTH TO SOUTHWEST FLOW OVER THE NORTH ALABAMA TAFS. 08/KEISER AT BMX /ISSUED 405 AM CDT TUE JUL 7 2015/ A LOW PRESSURE SYSTEM MOVING THROUGH SOUTHERN CANADA/GREAT LAKES REGION WAS NOTED ON SATELLITE IMAGERY THIS MORNING. A COLD FRONT EXTENDS SWWRD FROM THIS LOW INTO SW TEXAS. NAM/GFS/ECMWF GUIDANCE ARE ALL IN FAIR AGREEMENT IN DEVELOPING MULTIPLE WAVES ALONG THE COLD FRONT THROUGH WEDNESDAY. WHILE PROGRESSING THE COLD FRONT SLOWLY EASTWARD. BUT WITH THE ADVERTISED HIGH PRESSURE SYSTEM BEGINNING TO BUILD WESTWARD TODAY THESE STORMS WILL BE SHUNTED NORTHWARD AND MOST ACTIVITY SHOULD REMAIN IN TENNESSEE. THE HIGH PRESSURE/UPPER RIDGE BECOMES ANCHORED OVER THE SOUTHEASTERN STATES LATER THIS WEEK AND WILL RESULT IN HOT AND HUMID CONDITIONS.
Looking at the big picture, a rather broad trough resides across North America with a cutoff low spinning over the eastern Pacific. One of these little troughs is currently noted slowly moving east across Kansas and Oklahoma and it is this trough that will bring Wednesdays rain. The trough in southern Kansas will lift into Missouri early Wednesday. This should preclude much in the way of strong thunderstorm activity for Wednesday as the low moves through, but with perceptible water values between 1.

239 PM CDT TUE JUL 7 2015 COLD FRONT HAS CROSSED THE I-70 CORRIDOR EARLY THIS AFTERNOON. BUT HAVE FALLEN INTO THE LOWER 60S OVER THE NORTHEAST CWA NEAR CHAMPAIGN AND DANVILLE. BUT LOW CLOUDS GIVING WAY INTO MORE DIURNAL-TYPE CLOUDS FROM NORTH TO SOUTH AS HIGH PRESSURE BUILDS EAST ACROSS THE UPPER MISSISSIPPI VALLEY. AS LOW PRESSURE RIDES ALONG THE BOUNDARY INTO SOUTHWEST MISSOURI. WHICH SHOULD ALLOW TEMPERATURES TO DIP INTO THE LOWER 50S IN SOME OF THE NORMALLY COLDER SPOTS NORTH OF PEORIA AND BLOOMINGTON. MODELS PLACE THE HEAVIEST RAINFALL ALONG AND NORTH OF THE TRACK OF THE LOW. MODELS DIFFER ON TIMING OF THE LOW PRESS AREA. AFTER THIS LOW PRESSURE AREA MOVES THROUGH THERE COULD BE A BREAK IN THE PCPN.

HIGH PRESSURE AND DRIER AIRMASS OVER THE REGION SHOULD KEEP THINGS MOST DRY TODAY. WITH THIS HIGH PRESSURE OVER THE REGION TEMPS WILL BE SLIGHTLY WARMER THAN SEASONAL NORMS. THIS WAS CHARACTERIZED BY BUILDING MID AND UPPER LEVEL RIDGE BUT SIGNIFICANT LOW LEVEL MOISTURE TRAPPED WITHIN THIS RIDGE. WILL NEED TO WATCH LATE IN THE PERIOD AS UPPER RIDGE SHIFTS WEST ENOUGH TO ALLOW LOCAL AREA TO GET INTO NW FLOW. MODEL GUIDANCE IS RAMPING UP MAX TEMPS WITH EACH RUN AS RIDGE TAKES HOLD OVER THE AREA.
SLIGHTLY STRONGER DYNAMICS ARE IN PLACE ACROSS FAR SOUTHEAST MONTANA WHERE AN INVERTED TROUGH HAS BEEN SITUATED.
MEANWHILE, AN UPPER LEVEL LOW WILL START TO ENTER CALIFORNIA WITH A STRONG 250 MB JET EXTENDING ACROSS THE DESERT SOUTHWEST. AN AREA OF LOW PRESSURE WILL ALSO DEVELOP AROUND THE KS/CO BORDER WEDNESDAY LEADING TO SOUTHEASTERLY WINDS ACROSS THE CWA. PRECIPITATION CHANCES WILL IMPROVE WEDNESDAY NIGHT AS A WARM FRONT MOVES NORTH ACROSS SOUTHWEST KANSAS.

AN INFLUENCE FROM A NRN STREAM UPPER TROUGH WILL BRING A SLIGHT CHC FOR SHOWERS AND A FEW THUNDERSTORMS TO THE ERN PNHDL BY LATE EVENING. THE INCREASING CHCS ARE SUPPORTED BY THE MODELS INDICATING A SRN STREAM UPPER TROUGH APPROACHING FROM CO. AS THE SRN STREAM UPPER TROUGH LIFTS NORTHEAST. HIGHS PUSHED TOWARD THE WARMER NAM MET GUIDANCE FROM NEAR 80 AT VTN AND ANW TO THE LOWER 70S ERN PNHDL INTO THE OGA AREA.
309 PM CDT TUE JUL 7 2015 KSHV RADAR SHOWING SCT TSTMS ACROSS OUR EXTREME NRN SECTIONS IN ASSOCIATION WITH A WEAK COLD FRONT AND UPPER LEVEL DISTURBANCE.

233 PM EDT TUE JUL 7 2015 A COLD FRONT PUSHING THROUGH THE REGION TODAY WILL BRING WIDESPREAD SHOWERS AND THUNDERSTORMS.
The net effect of all this is the weak cold front that has been discussed the last few days, is moving farther south and east than earlier thought, aided by the previously mentioned convective cold pools.
1226 PM CDT TUE JUL 7 2015 THE SHORT TERM PERIODS WILL BE QUIET WEATHER WISE IN BETWEEN SYSTEMS ALOFT WHILE HIGH PRESSURE SETTLES IN AT THE SURFACE.

WEAK SURFACE RIDGING WITH RIDGING ALOFT WILL CONTINUE INTO THE UPCOMING WEEKEND. AS AN UPPER TROUGH DEVELOPS OVER THE EASTERN US. THIS UPPER TROUGH COUPLED WITH DIURNAL INSTABILITY WILL LEAD TO SCATTERED TO NUMEROUS AFTERNOON AND EVENING STORMS.
The current pressure analysis reveals a 1,020 millibar high pressure system centered over Cutbank, MT. Those areas that warm up and recover from the cooler morning conditions will be able to see more shower and thunderstorm development this evening.

OVERNIGHT LOWS MAY DROP INTO THE MID OR UPPER 30S FAR NORTH SO WILL ADD SOME PATCHY FROST LATE TONIGHT AS WELL AS FOG IN THE LOWER RIVER VALLEY REGIONS OF CENTRAL AND NORTH CENTRAL WISCONSIN.
AN UPPER LOW OFF THE COAST WILL MOVE INLAND LATE WEDNESDAY.
A COOLER AND DRIER AIRMASS WILL CONTINUE TO SETTLE ACROSS THE MIDWEST. HIGH PRESSURE WILL BUILD SOUTH ACROSS THE REGION THROUGH TONIGHT. THOUGH THE EXTENT OF COVERAGE MAY REMAIN LOW THROUGH TONIGHT AS EARLIER PROJECTIONS SUGGESTED THE HIGH WOULD KEEP THE PLUME MORE WEST OF THE AREA. H850 TEMPS REMAINING NEAR 9C BY 12Z WEDNESDAY AND RIDGE AXIS OVERHEAD. BY AFTERNOON H850 TEMPERATURES RECOVER TO THE LOWER TEENS WITH NORTHEAST FLOW.
246 PM EST SAT DEC 19 2015 HIGH PRESSURE SLIDES EAST ACROSS AREA THROUGH EARLY SUNDAY.
344 PM CST SAT DEC 19 2015 (Tonight and Sunday) A short wave ridge over the area this afternoon will transition to southwest flow aloft tonight and Sunday as an upper level trough moves inland from the California coast. With the increase in low level moisture and cloud cover, temperatures will be warmer overnight with lows mainly in the upper 40s.
WITH THE LOW-LEVELS MOISTENING AND COOLING OVERNIGHT. IT APPEARS THE LOW CLOUDS WILL MOVE IN FIRST AND THIS SHOULD KEEP VSBYS FROM DROPPING MUCH BELOW 3 MILES. REST OF THE FORECAST LOOKS TO BE IN GOOD SHAPE WITH AFTERNOON HIGHS MAINLY IN THE LOW TO MID 60S. SURFACE TO UPPER LEVEL RIDGING GIVES WAY AS AN UPPER LEVEL TROUGH CURRENTLY OFF THE WEST COAST MOVES TO THE GREAT BASIN AREA AS IT WEAKENS WITH SURFACE PRESSURES FALLING IN THE HIGH PLAINS.
1004 AM CST SAT DEC 19 2015 HIGH PRESSURE ACROSS THE GULF SOUTH WILL PROVIDE A VERY NICE DECEMBER DAY ACROSS THE FORECAST AREA. NEAR CLIMO HIGHS WILL OCCUR TODAY, HOWEVER THE RIDGE OF HIGH PRESSURE RESPONSIBLE FOR THE COOLER WEATHER WILL SHIFT EAST THIS MORNING ALLOWING A RETURN FLOW TO BECOME ESTABLISHED BY AFTERNOON. SUNDAY MORNING WILL BE NEARLY 10 DEGREES WARMER THAN THIS MORNING WITH HIGH TEMPS IN THE UPPER 60S TO AROUND 70 SUNDAY AFTERNOON.
