Alagasco Seven Day Forecast
Saturday afternoon, October 25, 2014
Forecaster: Ryan Stinnett
WONDERFUL WEEKEND: An area of high pressure remains the dominant feature providing terrific fall weather for all of Alabama this weekend. Both days will have full sunshine, fair nights, and a slow warming trend. We have climbed well into the 70s today, and a few spots could reach the low 80s tomorrow afternoon as the high pressure begins to slide across the area from west to east.
CONTIGUOUS TEMPERATURE EXTREMES: Yuma, Arizona, and Death Valley California were both 98F Friday afternoon. This morning, it was 21F at Gunnison, Colorado.
WEATHER ON THIS DATE IN 1921: A hurricane with 100 mph winds hit Tampa, Florida, causing several million dollars damage.
THE WORLD OF TROPICS: The Atlantic is mainly calm, with the once exception in the northwestern Caribbean as the remnants of tropical depression nine continue to linger and interact with a cold front. This system is producing disorganized showers and thunderstorms, and redevelopment, if any, will be slow to occur while it meanders for the next few days. In the Central Pacific, Ana is back up to hurricane strength and is moving towards the northeast. Ana is forecast to become extra tropical over the weekend, but will be impacting the Pacific northwest early next week.
SEVERE WEATHER OUTLOOK: Now that there are five severe weather categories, we are seeing these new categories go into use. The new “marginal” risk category has been issued for today for much of northern California and southwestern Oregon as a very strong storm system moves onshore. Scattered showers and thunderstorms are expected to develop in these areas from midday through this afternoon. A few of these may bring the risk of a weak/brief tornado.
FOR THE NEW WORK WEEK: The surface high pressure system will slide east of us Monday taking up a position centered over the Southeast Coast by Monday afternoon. Aloft an upper ridge will gradually move eastward too, locating along the eastern seaboard of the U.S. by late Monday. This should continue our dry weather with temperatures warming with morning lows approaching the 60s and a high in the lower 80s by Monday and lasting into midweek. By late Wednesday and into Thursday, a weak frontal boundary will move into the state and will provide a chance for rain. No impressive rainfall is expected, but a few showers will be possible.
