James Spann forecasts only isolated showers for Alabama from Alabama NewsCenter on Vimeo.

ONLY ISOLATED SHOWERS: Drier air continues to slip into Alabama this morning, and that will limit rain chances today. A few isolated showers or storms will be possible thanks to an unusually deep upper trough over the eastern third of the nation, but odds of any one spot getting wet today are only 15-20%. Otherwise, the day will be partly to mostly sunny with a high between 87 and 90 degrees.

REST OF THE WEEK: The weather won’t change much Wednesday through Friday. Expect mostly sunny days, fair nights and only isolated showers. Highs will be in the 88- to 92-degree range and lows will be in the upper 60s for most communities. The chance of any one location seeing a shower is only 10-15% each day.

THE ALABAMA WEEKEND: The quiet weather pattern continues. Look for a good supply of sunshine Saturday and Sunday with highs in the low 90s; the chance of a shower for any one spot is only about 5% Saturday and 15-20% Sunday.

NEXT WEEK: Moisture levels will slowly rise and we will see the return of random, scattered, mostly afternoon and evening showers and thunderstorms on most days with highs remaining in the low 90s, right at seasonal averages for mid-August.

ISAIAS IS INLAND: Isaias made landfall as a Category 1 hurricane last night on the southern North Carolina coast just below Wilmington. It will race to the northeast today, bringing wind and rain along the path.

Isaias is expected to bring widespread sustained tropical-storm-force winds and wind gusts to hurricane force to the mid-Atlantic coast, including portions of the Chesapeake Bay region, through this afternoon, which could cause tree damage and power outages. Tropical storm conditions are expected to spread across New England tonight.

Heavy rainfall along the East Coast, near the path of Isaias, will result in flash flooding, some of which may be significant in North Carolina through the Mid-Atlantic and Northeast through tonight. Potentially life-threatening urban flooding is possible in D.C., Baltimore and elsewhere along and just west of the I-95 corridor today. Widespread minor to moderate river flooding is likely across portions of the Carolinas and the Mid-Atlantic. Quick-responding rivers in the Northeast will also be susceptible to minor river flooding.

Tornadoes have already occurred over portions of northeastern North Carolina and southeastern Virginia overnight. The threat of tornadoes will spread northward along the mid-Atlantic coast today and then across New England by tonight.

INVEST 94L: The disturbance south of Bermuda seems to be dissipating due to very dry air surrounding the system, and the rest of the Atlantic basin is quiet this morning.

ON THIS DATE IN 2009: The strongest tornado to hit Quebec since the same date in 1994 ripped through Mont-Laurier. The F2 tornado tore through the small western Quebec town, severely damaging about 40 homes. Two men were taken to the hospital with minor injuries.
