Isolated Showers Today, Then Mostly Dry

| August 3, 2020 @ 5:56 am

RADAR CHECK: We have a few small, isolated showers over Alabama early this morning ahead of an unusually strong upper trough for summer approaching from the west. Showers should push east of the state later today as the trough axis passes through; the day will be partly sunny with a high at or just over 90 degrees.

REST OF THE WEEK: Precipitable water values will drop as dry air rolls into the state, and most communities will be rain-free tomorrow through Friday with only a slight risk of a shower each day. Afternoon highs will be close to 90, but on the positive side humidity values will be lower, and nights cooler. Early morning lows will drop into the 60s, pretty comfortable for August in Alabama. Days will be mostly sunny, nights will be clear.

THE ALABAMA WEEKEND: The weather stays dry with a trend toward hotter afternoons; we could easily see mid 90s by Saturday and Sunday. The risk of an afternoon shower both days is very low, but not zero.

NEXT WEEK: Moisture levels rise, and we will bring back the usual risk of random, scattered, afternoon and evening showers and thunderstorms each day. The sky will be partly sunny on a daily basis with highs in the low to mid 90s. See the Weather Xtreme video for maps, graphics, and more details.

ISAIAS UPDATE: Tropical Storm Isaias, now with 70 mph winds about 115 miles east of Jacksonville, is expected to reach category one hurricane strength by the time it moves into the coast of the Carolinas tonight. A Hurricane Warning has been issued from South Santee River South Carolina to Surf City North Carolina.

There is the danger of life-threatening storm surge inundation along portions of the immediate coastline and adjacent waterways of northeastern South Carolina and southern North Carolina. Life-threatening storm surge is possible along the North Carolina coast from Cape Fear to Duck. Residents in these areas should follow advice given by local emergency officials. Heavy rainfall will result in flash and urban flooding, some of which may be significant in the eastern Carolinas and the mid-Atlantic, through midweek along and near the path of Isaias across the East Coast of the United States. Widespread minor to moderate river flooding is possible across portions of the Carolinas and the mid-Atlantic.

INVEST 94L: Recent satellite-derived wind data indicate that the area of disturbed weather located a few hundred miles north of the northern Leeward Islands does not have a surface circulation, and the associated shower activity is not well organized. However, environmental conditions could allow for some slow development of this system during the next several days, with a tropical depression possibly forming later this week. This system is forecast to move northwestward at about 15 mph over the southwestern Atlantic today and on Tuesday and then stall several hundred miles southwest of Bermuda by the middle to latter part of the week. For now it looks like it will remain east of the U.S.

The rest of the Atlantic basin is quiet.

ON THIS DATE IN 1970: Hurricane Celia made landfall near Port Aransas, Texas as a major Hurricane, Category 3 on the Saffir-Simpson scale with sustained winds of 130 mph. It was the costliest tropical cyclone in Texas history until Hurricane Alicia in 1983. Throughout the state, 8,950 homes were destroyed and damaged about 55,650 others. About 252 small businesses, 331 boats, and 310 farm buildings were either damaged or destroyed. Impact was the worst in Nueces County, which observed gusts as high as 180 mph. In Corpus Christi, about one-third of houses suffered severe damage or were destroyed. Additionally, about 90% of the buildings in downtown were damaged to some degree. Celia weakened as it continued further inland and dissipated over New Mexico on August 6.
