A COLD FRONT WILL MOVE SOUTHEAST THROUGH THE AREA EARLY THIS
MORNING. IN THE WAKE OF THIS FRONT, THERE WILL BE SCATTERED
RAIN SHOWERS. WHILE THE RADAR IS SHOWING QUITE A FEW SHOWERS,
THE SOUNDINGS SHOW QUITE A BIT OF DRY AIR BELOW 700 MB, SO THERE
IS QUITE A BIT OF UNCERTAINTY ON WHETHER ANY OF THIS RAIN IS
ACTUALLY MAKING IT TO THE SURFACE. AS A RESULT, WENT WITH RAIN
SHOWERS AND SCATTERED SPRINKLES IN THE FORECAST.
IFR/MVFR CEILINGS WILL MOVE INTO THE AREA THIS MORNING AND THEN
GRADUALLY DISSIPATE THIS AFTERNOON AS HIGH PRESSURE GRADUALLY
