Occasional Tropical Showers Through Tomorrow

| July 7, 2020 @ 3:14 pm

VERY HUMID DAY: A blanket of moist air continues to cover Alabama today, and we have a number of showers and thunderstorms on radar at mid-afternoon. Like yesterday, they are very effective rain producers thanks to the tropical airmass in place; motion today is to the south/southeast. Nothing severe, and not much lightning. The showers will persist well into the night as a broad upper trough remains over the region.

Temperatures remain below average; mostly in the low to mid 80s with only a limited amount of sun today. The average high for Birmingham on July 7 is 91.

REST OF THE WEEK: The overall situation won’t change much tomorrow; more clouds than sun with scattered to numerous showers and thunderstorms… highs will remain in the 80s. Then, on Thursday and Friday showers and storms should be a little more scattered in nature, and mostly during the afternoon and evening hours. Heat levels will rise with a high around 90 Thursday, followed by low 90s Friday.

THE ALABAMA WEEKEND: The weather looks relatively dry Saturday and Sunday with only isolated afternoon storms; otherwise look for partly to mostly sunny days with highs between 91 and 95 degrees. We do note we will be in a broad northwest flow pattern, meaning organized thunderstorm areas that form over states like Missouri and Arkansas will have potential to roll down into our state. No way of knowing now if, or when it will happen… just a possibility.

NEXT WEEK: The pattern looks very routine for mid-summer. Hot, humid days… a partly sunny sky, and the daily chance of random, scattered, mostly afternoon and evening showers and thunderstorms. Highs will remain in the low to mid 90s… See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: An area of low pressure located inland over northeastern Georgia continues to produce a large area of showers and heavy rain over portions of the southeastern U.S. The low is expected to move generally northeastward toward the coast of the Carolinas and the mid-Atlantic states and some development of this system is possible later this week if it moves over water. Regardless of development, the low is forecast to produce locally heavy rainfall that could cause flash flooding across portions of the southeastern U.S. during the next couple of days.

The rest of the Atlantic basin, including the Gulf of Mexico, remains very quiet.

UPDATED HURRICANE SEASON FORECAST: An updated seasonal hurricane forecast from Phil Klotzbach and his group at Colorado State was released this morning: They continue to call for a very active 2020 Atlantic hurricane season. The new forecast calls for 20 named storms (including the 5 that have already formed), 9 hurricanes and 4 major (Cat 3+) hurricanes. CSU has chosen six analogs for its July seasonal hurricane forecast: 1966, 1995, 2003, 2008, 2011 and 2016. All of these years had above-average Atlantic hurricane activity and were generally characterized by cool neutral ENSO or LaNina conditions and warm tropical Atlantic.

ON THIS DATE IN 2004: A tornado occurred in the Rockwell Pass area of Sequoia National Park, California. Since the elevation of the tornado’s ground circulation was approximately 3705 m (12,156 ft) MSL, this is the highest-elevation tornado documented in the United States.
