Daily Summary from the VU Weather Center

For , Wednesday

CURRENT SATELLITE AND WATER VAPOR SHOW A SHORTWAVE TROUGH AXIS CURRENTLY OVER THE VALPARAISO AREA. THIS WILL ACT TO PRODUCE ENOUGH LIFT TO SUPPORT AND FURTHER DEVELOP STRATOCUMULUS AND ALTOCUMULUS CLOUD COVER THROUGHOUT THE REST OF THE AFTERNOON...ALONG WITH STRATOCUMULUS STREAMING IN FROM THE NORTHWEST. A STRAY RAIN SHOWER CANNOT BE RULED OUT UNTIL THIS TROUGH COMPLETELY EXITS THE REGION OVERNIGHT. TO THE WEST OF THIS BATCH OF CLOUD COVER...A HIGH PRESSURE SYSTEM SITS OVER THE GREAT PLAINS. THIS WILL KEEP US DRY THROUGH AT LEAST THE END OF THE WEEK. CLOUD COVER WILL WORK ITS WAY IN FROM THE WEST LATER IN THE DAY ON FRIDAY. A SYSTEM TO OUR NORTH WILL BRING SLIM CHANCES FOR A STRAY SHOWER ON SATURDAY AS FLOW FROM THE SOUTHWEST WILL BUILD IN BEHIND THE EXITING HIGH PRESSURE SYSTEM TO OUR EAST. THE NEXT REAL DECENT CHANCES FOR RAIN LOOK TO BE EARLY NEXT WEEK HEADING INTO MONDAY NIGHT AS A PLUME OF MOISTURE WORKS ITS WAY UP FROM THE GULF OF MEXICO...AND COMBINES WITH A FRONTAL BOUNDARY WORKING ITS WAY ACROSS THE CENTRAL UNITED STATES. DRY CONDITIONS WILL WORK THEIR WAY BACK IN AFTER THIS...AS A HIGH PRESSURE SYSTEM AND SUBSIDENCE BUILDS IN FOR EARLY TO MID NEXT WEEK. UNTIL THEN...TEMPERATURES WILL REMAIN ON THE COOL SIDE THROUGH THURSDAY. FRIDAY LOOKS WARMER WITH TEMPERATURES IN THE MID TO UPPER 50S AS WARM AIR WORKS ITS WAY IN AS A RESULT OF SOUTHERLY FLOW WITH THE RIDGING AND HIGH PRESSURE MOVING OFF TO THE EAST. THE WEEKEND LOOKS WARMER WITH WARM AIR ADVECTION CONTINUING TO WORK ITS WAY IN AND KEEP TEMPERATURES IN THE 60S FOR HIGHS AND MID 40S FOR LOWS. COOLER AIR WILL WORK IN DURING THE EARLY TO MID PORTIONS OF NEXT WEEK BEHIND THE PRECIPITATION AND IN ADVANCE OF HIGH PRESSURE.
