A RIDGE OF HIGH PRESSURE WILL REMAIN IN PLACE OVER THE CALIFORNIA COAST MAINTAINING SLIGHTLY WARMER THAN NORMAL TEMPERATURES AND DRY WEATHER THROUGH WEDNESDAY.
917 PM CST WED JAN 14 2015 A SHORT WAVE TROUGH WILL CONTINUE TO MOVE ACROSS FAR WEST TEXAS THIS EVENING. THE SHORT WAVE WILL CONTINUE TO WEAKEN AS IT MOVES EAST TROUGH THE NIGHT.
UPPER AIR ANALYSIS THIS MORNING SHOWED ZONAL FLOW ACROSS THE SOUTHERN HALF OF THE COUNTRY WITH A CLOSED LOW AND SHARPLY TILTED TROUGH OVER THE SOUTHWEST.
A TROUGH AXIS SLIDING ACROSS THE REGION WILL BRING SCATTERED SHOWERS TO THE AREA.
THE WEAK DISTURBANCE THAT PRODUCED PATCHY FREEZING DRIZZLE AND A LIGHT DUSTING OF SNOW FOR PARTS OF THE MID STATE THIS MORNING HAD WEAKENED AND MOVED OFF TO THE EAST. KEEPING TEMPS AROUND FREEZING. FREEZING TEMPS WILL STILL BE IN PLACE. ANY SNOW THAT DOES OCCUR WILL MELT QUICKLY WITH HIGHS EXPECTED TO REACH THE LOWER 40S ACROSS THE MID STATE.
912 PM CST WED JAN 14 2015 MID AND HIGH LEVEL CLOUDS ARE QUICKLY INCREASING ACROSS THE MIDSOUTH AHEAD OF THE UPPER LEVEL TROUGH APPROACHING FROM THE WEST. UPPER LEVEL TROF WILL APPROACH FROM THE WEST WITH MID AND HIGH CLOUDS INCREASING OVERNIGHT. MOST OF THE LARGER SCALE MODELS ARE DEPICTING THIS BAND STREAKING EAST ACROSS MISSOURI AND IT SEEMS TO BE CAUSED BY AN INTERACTION BETWEEN THE STRONG UPPER JET PUNCHING INTO THE LOWER MS VALLEY AND ANOTHER JET LIFTING INTO THE SOUTHERN GREAT LAKES. UPPER TROUGH WILL MOVE THROUGH IN THE MORNING.
WEAK TROUGH WILL CONTINUE TO PUSH ACROSS THE STATE THROUGH THIS EVENING AND LOOKS TO BRING A LITTLE CLOUD COVER INTO THIS EVENING. LEANED TOWARD A SLIGHTLY WARMER FORECAST FOR TEMPERATURES TONIGHT. ANOTHER UPSTREAM CLIPPER OVER CANADA AND A TROUGH OVER MONTANA THIS MORNING WILL TRACK SOUTHEAST WITH THE TROUGH ARRIVING OVER IOWA ON THURSDAY.

702 PM EST WED JAN 14 2015 A LARGE AREA OF HIGH PRESSURE WILL MAINTAIN CONTROL OF OUR LOCAL WEATHER THROUGH MUCH OF THURSDAY.
TEMPS ARE RUNNING ABOUT A DEGREE OR TWO WARMER THAN ANTICIPATED BUT MORNING LOW FCST STILL LOOKS GOOD.
CURRENT READINGS ACROSS THE HIGH PLAINS OF KANSAS AND NEBRASKA ARE RUNNING WELL ABOVE GUIDANCE PROJECTIONS SO CONFIDENCE IS HIGH IN THIS SCENARIO PLAYING OUT.
A WEAK LOW PRESSURE SYSTEM AHEAD OF THE MAIN SYSTEM OVER THE EASTERN PACIFIC WILL BRING A THREAT OF RAIN TO THE COAST LATER TONIGHT.
DID ALSO GET A REPORT OF FREEZING RAIN ON THE BACK EDGE OF THIS PRECIP. WHILE MODEL SOUNDINGS INDICATE THERMAL PROFILES GENERALLY BELOW FREEZING AT 00Z. WARMER AIR ALOFT IS PUSHING IN WHICH MAY BE MORE PRONOUNCED THAN MODELS INDICATE AT THIS TIME. THIS AREA CORRESPONDS TO A NICE COMPACT PIECE OF SHORT WAVE ENERGY AND WARMER 925MB TEMPS. THESE WARMER TEMPS WILL CONTINUE TO PUSH EAST LEADING TO A MILD NIGHT. HIGH PRESSURE BUILDS IN FOR THU/THU NIGHT. MODELS STILL INDICATE THE POTENTIAL FOR A LITTLE LIGHT PCPN ON THE BACK SIDE OF THE HIGH.
EXCEPTION WILL BE THE HIGH MOUNTAIN VALLEYS WHERE AREAS OF STRATUS LINGER.
S/W TROF WILL MOVE FROM MANITOBA TO NORTH OF LK SUPERIOR BY THURSDAY MORNING. A NARROW WARM SECTOR WILL ADVECT EASTWARD ACROSS MUCH OF THE DULUTH CWA OVERNIGHT WHICH WILL ACT TO WARM THE LOWER LEVELS RATHER SIGNIFICANTLY FROM WHAT THEY WERE OVER THE PAST SEVERAL DAYS.

DRIER AND WARMER CONDITIONS RETURN FOR THE WEEKEND. SO STILL EXPECT THE LOW CLOUDS AND LIGHT NORTHERLY WINDS TO REMAIN OVERNIGHT AS LONG AS THE WEDGE HOLDS.
WITH THE MAJORITY OF THE LOW LEVEL MOISTURE HAVING A BETTER CHANCE OF BEING LOW STRATUS INSTEAD OF GROUND FOG ACROSS MUCH OF THE AREA. NORTH AND NORTHEAST WINDS CONTINUE FOR THE NEXT SEVERAL DAYS AS HIGH PRESSURE WILL REMAIN NORTH OF THE WATERS OVER AREAS FROM TEXAS TO VIRGINIA.
DEVELOPING SYSTEM THOUGH OVER THE WRN GULF WILL QUICKLY GET PICKED UP BY A TROUGH PATTERN DIVING INTO THE PLAINS STATES HEADING INTO THE MORNING HRS THU. 09 /ISSUED 116 PM CST WED JAN 14 2015/ VIS IMAGERY SHOWS A MORE RAPID EROSION OF THE LOW CLOUD DECK ACROSS MIDDLE TN INTO NWRN AL. WATER VAPOR IMAGERY SHOWS THE UPPER LOW DROPPING SEWD ALONG THE MOGOLLON RIM AND WILL BEGIN SHEARING OUT AND SPEEDING EWD THRU TX AND THE GULF STATES LATE TONIGHT INTO THURSDAY. WE WILL HAVE TO MONITOR TRENDS CLOSELY, BUT AT THIS TIME, THE LOWEST 1-2KFT WILL BE JUST ABOVE FREEZING THRU THE DAY ON THURSDAY, MAINTAIN LIQUID PRECIP.

EVEN AS LIGHT NORTHERLY WINDS CONTINUE TONIGHT STRONG RADIATIONAL COOLING SHOULD OCCUR WITH A DEEP DRY LAYER UNDER THE UPPER RIDGE.
THE 16Z SURFACE ANALYSIS INDICATED THAT A SURFACE COLD FRONT WAS MOVING SOUTHEAST THROUGH CENTRAL ILLINOIS. WITH CONTINUED WARM ADVECTION THIS AFTERNOON IN ADVANCE OF THE COLD FRONT. EXPECT TEMPS TO WARM TO THE LOWER TO MID 60S EVEN WITH LOW TO MID CLOUDS ACROSS THE REGION. AS LOW LEVEL MOISTURE INCREASES AHEAD OF AN APPROACHING COLD FRONT.
A COLD FRONT IS CURRENTLY LOCATED FROM NORTHWEST INDIANA THROUGH CENTRAL MISSOURI AND INTO THE TEXAS PANHANDLE. NOT MUCH IN THE WAY OF CLOUDS AHEAD OF THE FRONT AT THIS TIME BUT THERE IS STILL A SMALL CHANCE OF LIGHT RAIN DEVELOPING ACROSS THE FORECAST AREA AS THE COLD FRONT APPROACHES. THE SOUTHWESTERLY FLOW WILL KEEP TEMPERATURES MILD WITH MOST LOCATIONS REACHING INTO THE LOWER AND MIDDLE 60S. A WEAK COLD FRONT MOVING SOUTHEAST OUT OF THE CENTRAL PLAINS TODAY WILL CROSS THE MID SOUTH OVERNIGHT. TEMPERATURES ON MONDAY SHOULD BE COOLER AND DROP BACK TO SEASONABLE LEVELS FOR THIS TIME OF YEAR.
