MAIN FORECAST CHALLENGES REMAIN THE TIMING AND STRENGTH OF TWO APPROACHING FRONTAL BOUNDARIES...ONE THIS WEEKEND AND THE SECOND LATE TUESDAY/EARLY WEDNESDAY. THE FIRST FRONTAL BOUNDARY LOOKS TO BEGIN MOVING OVER THE CWFA LATE SATURDAY INTO EARLY SUNDAY MORNING. BOTH THE ETA AND AVN HAVE TRENDED TOWARDS SLOWING THIS BOUNDARY DOWN ON SUNDAY. THIS SEEMS REASONABLE AS THE 500MB FLOW IS PRETTY MUCH PARALLEL TO THE FRONT AT THIS TIME. THE BOUNDARY BECOMES STATIONARY SUNDAY OVER CENTRAL VA THROUGH MONDAY. CONVECTION ALONG THE FRONT STILL LOOKS GOOD FOR SATURDAY NIGHT AND SUNDAY. THE MODELS HAVE CONTINUED TO DESTABILIZE THE ATMOSPHERE RUN TO RUN. IN ADDITION...WILL HAVE SOME UPPER AIR SUPPORT WITH THE RRQ OF A 250MB JET SWIPING THE CWFA ON SATURDAY NIGHT. UNSETTLED WEATHER SHOULD CONTINUE ON INTO THE EARLY PART OF SUNDAY...WITH A SURFACE WAVE DEVELOPING ALONG THE FRONT. TEMPERATURES SHOULD BE SLIGHTLY COOLER BEHIND THE BOUNDARY...HOWEVER THE CWFA NEVER GETS INTO THE UPPER NORTHWESTERLY THAT WOULD BRING IN THE MUCH COOLER TEMPERATURES. FRONT IS PROGGED TO RETREAT BACK NORTHWARD LATE SUNDAY INTO MONDAY. THE MODELS HAVE SPED UP THE APPROACH OF THE MID WEEK FRONTAL BOUNDARY TO LATE TUESDAY/EARLY WEDNESDAY FROM LATE WEDNESDAY/EARLY THURSDAY. NOT QUITE CONFIDENT IN THIS TREND...HOWEVER...NO MATTER HOW YOU LOOK AT IT...A FRONT WILL APPROACH ON WEDNESDAY. THIS BOUNDARY SHOULD ALSO STALL IN THE VICINITY OF THE CWFA AND TEND TO FOCUS SHOWERS AND THUNDERSTORMS FOR THE REMAINDER OF THE WEEK. LISTEMAA && .LWX WATCHES/WARNINGS/ADVISORIES... DC...NONE.
