THE WEATHER PATTERN

Here is my weekly weather quiz question for the last time. What is “NEXRAD”? Here is the correct answer. NEXRAD is NEXt Generation RADar. A NWS network of about 140 Doppler radars operating nationwide.

Upper Level Low Pressure sends a series of frontal systems our way bringing much needed rain. The graphics for days 1-3  show a cold front approaching the coast Saturday. The graphics for days 3-7     Tuesday through Saturday show a frontal system that pushed through Monday and Monday night, then the next one  slides through the Pacific Northwest Wednesday.

Note: The Autumnal Equinox occurred last night at 11:50 PM. That makes today the first full day of Autumn (Fall).
