AFTER MORNING FOG DISSIPATES/EVAPORATES, THE MAIN STORY WILL BE THE TEMPERATURES WITH AMPLE DAYTIME HEATING/WAA CONTRIBUTING TO DAYTIME HIGHS IN THE LOW TO MID 80S. CURVED HODOGRAPHS IN THE LOW TO MID LEVELS SUPPORT THE POSSIBILITY FOR DISCRETE CELLS BUT WITH GENERALLY WEAK FLOW, MERGING OF CELLS WITH THE LINE LOOKS TO BE A POSSIBILITY AS WELL.
WITH ITS RIDGE AXIS TO OUR NORTH. EXCEPT COOLER AT THE COAST. HIGH PRESSURE TO OUR NORTH WILL KEEP EAST TO SOUTHEAST WINDS IN PLACE FOR THE NEXT FEW DAYS.
653 AM CDT WED APR 8 2015 LATEST WATER VAPOR SATELLITE IMAGERY SHOWING SOUTHWESTERLY FLOW ALOFT ACROSS CENTRAL PLAIN STATES AND UPPER LEVEL TROUGH OVER THE WESTERN UNITED STATES. LIFT AND MOISTURE ASSOCIATED WITH THE OPEN UPPER LEVEL WAVE WOULD QUICKLY MOVE EAST BEFORE THE ATMOSPHERE COLUMN COOLS DOWN TO BELOW OR AT FREEZING.
1112 AM EDT WED APR 8 2015 A NEARLY STATIONARY FRONT JUST SOUTH OF PENNSYLVANIA WILL COMBINE WITH STRONG HIGH PRESSURE OVER QUEBEC TO KEEP MOIST AND COOL CONDITIONS OVER THE REGION THROUGH THURSDAY.
At the surface, a high pressure ridge axis roughly north-south along 106W will persist. High temperatures today will be several degrees cooler than yesterday, generally in the 60s to near 70 degrees area-wide, still pretty close to normal for this time of year.
419 PM EDT SAT MAR 14 2015 HIGH PRESSURE WILL BUILD EAST ACROSS THE AREA THROUGH THE WEEKEND.
HIGH PRESSURE ALOFT AND WEAK OFFSHORE FLOW WILL CONTINUE VERY WARM MID-MARCH WEATHER THROUGH SUNDAY.
THE AFTERNOON UPDATED FEATURED A DROP OF THE AREAL FLOOD WATCH AS RAIN AREA HAS BEEN PUSHED EASTWARD AS SURFACE COLD FRONT IS PROGRESSING RAPIDLY ACROSS OHIO WITH DEEPENING UPPER LOW TO THE NORTH OF THE GREAT LAKES. COLD ENOUGH FOR SOME SNOW SHOWERS WITH THE RESIDUAL PRECIPITATION UNDER THE CROSSING MID LEVEL TROUGH AXIS. GIVEN THE LOW FORECAST INVERSION LEVELS. THAT UPPER TROUGH IS EXPECTED TO MAINTAIN SUFFICIENT SHALLOW CONVECTIVE POTENTIAL FOR SOME ISOLATED TO SCATTED RAIN AND SNOW SHOWERS EARLY SUNDAY AS IT DIGS EASTWARD. NONE OF THAT WILL BE SIGNIFICANT AND WILL BE SUPPRESSED VIA BUILDING HIGH PRESSURE AS THE DAY PROGRESSES. WIND GUSTS WERE THUS ADJUSTED WITH 35 TO 40 MPH ANTICIPATED ON THE HIGHER ELEVATIONS.
403 PM EDT SAT MAR 14 2015 HIGH PRESSURE WILL BE BUILDING IN ACROSS THE REGION FROM THE WEST TONIGHT WHILE A TROUGH LINGERS ACROSS THE EASTERN GREAT LAKES.

1224 PM CDT Sat Mar 14 2015 A weak cold front has pushed across Illinois with N winds 10-15 mph bringing a drying trend through central Illinois this morning. High temperatures today should reach around 60 or slightly warmer. 07z/2am surface analysis shows low pressure over Arkansas with stationary frontal boundary extending northeastward into the Ohio River Valley. A cold front currently across west-central Illinois will push eastward over the next few hours, introducing northwesterly winds and rapidly improving visibilities. Despite FROPA and northwesterly winds, airmass behind the boundary is only slightly cooler. High pressure will control the weather across central Illinois on Sunday, providing plenty of sunshine and light winds. Thanks to light southerly winds developing by afternoon and the mid-March sun warming the dry airmass, high temperatures will reach the lower to middle 60s.
TEMPERATURES SHOULD BE AT LEAST AS WARM IF NOT SLIGHTLY WARMER THAN SUN. TEMPERATURES COULD BE SIGNIFICANTLY WARMER ACROSS SOUTHERN SECTIONS IF FRONT STALLS A BIT FURTHER NORTH AND MINIMUMS WOULD BE HIGHER WITH THE INCREASING LOW LEVEL MOISTURE. AS HIGH PRESSURE CONTINUES TO DROP SOUTHEAST ACROSS CENTRAL AND EASTERN KANSAS THIS AFTERNOON AND EVENING. THIS WILL KEEP GFDI VALUES IN THE HIGH CATEGORY TODAY.
EXPECT WARM ADVECTION TO START LATER THIS EVENING AS WINDS BECOME MORE SOUTH TO SOUTHWESTERLY AND THE UPPER RIDGE CONTINUES TO BUILD OVER THE AREA. SOUTH WINDS TO REMAIN UP IN SPEED TONIGHT AND TEMPERATURES TONIGHT AS A RESULT WILL REMAIN QUITE MILD AS LOW LEVEL THERMAL RIDGE IS OVER THE FORECAST AREA. ISSUE SUNDAY IN REGARDS TO TEMPS IS THE COLD FRONT TIMING. GFS MODEL REMAINS THE FASTEST IN BRINGING COLD FRONT THRU SUN AFTN-EVE.
COLD FRONT CONTINUES TO TRACK SOUTHEAST AND WILL ENTER THE MID-STATE EARLY THIS AFTERNOON. /ISSUED 1014 AM CDT SAT MAR 14 2015/ COLD FRONT JUST UPSTREAM CONTINUES TO TRACK SOUTHEAST AND IS EXPECTED TO PUSH ACROSS THE MID-STATE THIS AFTERNOON. WINDS SHOULD WORK THEIR WAY FROM SOUTHERLY TO MORE NORTHERLY AS THE COLD FRONT SLIDES THROUGH THE REGION BUT SHOULD REMAIN BELOW 10 KNOTS. 00Z MODELS INDICATE A COLD FRONT WILL PUSH SOUTHWARD INTO AND ACROSS THE FORECAST AREA TODAY.
MET GUIDANCE LOWS TONIGHT ARE SEVERAL DEGREES WARMER THAN THE MAV, SO WILL AT LEAST TREND ABOVE THE MAV FOR TEMPS.
AN INVERTED TROUGH AXIS OVER THE WESTERN GULF OF MEXICO INTO DEEP SOUTH TEXAS WILL APPROACH THE SOUTHERN COASTAL BEND SUNDAY MORNING TO PROVIDE A CHANCE OF SHOWERS BUT CLOUD DECK SHOULD REMAIN AROUND 4-5 KFT.

THE STRONG HIGH PRESSURE RIDGE OVER CENTRAL CALIFORNIA WILL GRADUALLY WEAKEN AND SHIFT INLAND.
COLD FRONT STILL ON TRACK TO CLEAR THE STATE AROUND SUNRISE. AND WIND SHIFT TO THE NORTHWEST WILL LEAD TO DRYING AND SCOURING OUT OF THE LOW CLOUDS. UPPER LEVEL TROUGH AXIS/COLD POOL (850 MB TEMPS OF -4 TO -7 C) DOES NOT ARRIVE UNTIL 00Z SUNDAY. BUT LOW CLOUDS WILL PROBABLY PERSIST AS MOISTURE IS TRAPPED UNDERNEATH THE LOWERING INVERSION.
348 PM CDT SAT MAR 14 2015 WARM SPRING AFTERNOON ACROSS THE AREA WITH MOST LOCATIONS SEEING READINGS IN THE MID/UPPER 70S (ABOUT 10 DEGREES COOLER UNDER THE CLOUDS ACROSS NE PARTS OF CWA).

WILL SEE A SFC TROF MOVE ACROSS THE AREA BRINGING MORE WESTERLY WINDS. WITH SOME LOCATIONS REACHING THE LOW 70S. COOLER AIR IS LAGGING MUCH FARTHER NW BEHIND THE SFC TROF.
305 PM CDT Sat Mar 14 2015 High pressure will move over central Illinois from the northern Plains tonight bringing a decrease in wind speeds as well as decreasing high cloudiness. Temperatures will cool quite substantially in a very dry atmosphere and clear skies, so expecting lows to reach close to the freezing mark. High pressure will settle over Illinois on Sunday, providing subsident air and dry conditions.
HIGH PRESSURE NOW BUILDING STRONGLY OVER SE CO WITH LOTS OF SUN AND TEMPS CLIMBING INTO THE 60S OVR THE PLAINS. THE RIDGE WILL KEEP US DRY AND WARM THROUGH SUNDAY.
IT WILL TAKE A WHILE TO MIX OUT THE LOW CLOUDS BUT WITH SOUTHERLY FLOW WE SHOULD STILL BE ABLE TO WARM UP NICELY. AND TEMPERATURES AROUND 70 TO THE LOWER 70S WILL STILL BE ATTAINABLE. ONLY KMGM AND KTOI HAVE BROKEN OUT OF THE LOW CIGS AND WILL REMAIN VFR THROUGH THE REST OF THE AFTERNOON.

Upper high gaining amplitude over NorCal Today. Upper ridge amplifies across the region today and Wednesday as the upstream trough develops off the west coast. This will lift the warm front that's been draped across the far northern portion of the state further to the north ending the threat of showers for the northern Sacramento Valley and northern mountains. A disturbance moving over a flattened ridge may bring an increase in showers to areas north of Red Bluff late tonight and Tuesday morning.
