PASSAGE ACROSS EASTERN ID DURING THE MORNING HOURS WITH THE NGM ABOUT
4 TO 6 HOURS EARLIER THAN THE ETA.  TONIGHT WILL BE A WARM NIGHT AS
SOUTHWEST FLOW INCREASES AHEAD OF FRONT.  SCATTERED SHOWERS AND
THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND LINGER THROUGH MUCH OF
TONIGHT AND INTO THE MORNING HOURS ALONG THE FRONT.  TEMPERATURES

THICKNESSES ESPECIALLY IN THE AFTERNOON HOURS AS COLD AIR ADVECTION
