Much of the country will enjoy a calm and warm Halloween today as high pressure dominates the weather forecast into Saturday. The only exceptions will be the West Coast, especially the Pacific Northwest, where a persistent light to moderate rain will fall throughout much of the day. A brief break in the rain can be expected later in the evening and into the early nighttime hours across the Pacific Northwest before another stronger system begins affecting the region on Saturday. A few spotty showers with an ocassional thunderstorm are possible across the panhandle of Florida and parts of Missouri and Arkansas.
Aside from the rain along the West Coast, the main weather story today will be the warm temperatures extending into the Northern Plains region around the backside of high pressure along the Southeast coast. Daytime high temperatures well into the 70s and 80s can be expected from Texas northward into South Dakota, which will give way to very comfortable early evening temperatures just in time for the trick-or-treaters. Cooler temperatures will be found across northern sections of New England along the Canadian border as a cold front brushes the area. For the West Coast, temperatures during the day will not change all that much across the Pacific Northwest under cloud cover and rain showers. Expect early evening temperatures in the 50s west of the Cascades, and slightly cooler on the leeward side with temperatures falling into the mid and upper 40s.
