Dry today; Tropical rain during the weekend: the Alabama weather blog
STILL DRY TODAY: Temperatures are between 58 and 64 degrees across much of Alabama early this morning, we expect another mostly sunny day with a high of around 90 degrees this afternoon. The average high for Birmingham on June 17 is 89.
The northern 2/3 of the state will remain dry tomorrow with a high in the 1990s, but a tropical system in the Gulf of Mexico will bring rain to the southwestern corner of the state in the afternoon.
SATURDAY TO MONDAY: A tropical depression will sweep through the area, causing a statewide soak over the weekend. Rain over southern Alabama on Friday evening will extend northward on Saturday morning, and most of the state will be in rain on Saturday afternoon and evening. The rain continues on Saturday night and Sunday, and the rain could be heavy at times. The tropical depression will move to northeast Alabama by Sunday evening, but very deep humidity will remain behind and spells of rain will continue from Sunday evening through Monday.
Rainfall amounts for much of Alabama from tomorrow through Monday will be in the range of 3 to 6 inches, with the potential for larger totals in places, especially in southwestern counties. Flooding is very possible over the weekend.
A few brief, isolated tornadoes will be possible Saturday afternoon, Saturday evening and early Sunday over southern Alabama; The SPC has defined a “marginal risk” (level 1/5) for the southwest corner of the state. This could be extended later as the tropical system evolves.
REST OF NEXT WEEK: The probability of rain, accompanied by a few thunderstorms, will remain fairly high on Tuesday as a cold front approaches. Then the weather patterns dry up in the second half of the week. Peaks will be in the mid-80s most of the time… See the Weather Xtreme video for maps, graphics and more details.
TROPICS: The vast low pressure area located on the eastern part of Campeche Bay produces widespread cloudiness, disorganized showers and a few thunderstorms. This system will move little today, and little or no development is expected during this time due to interaction with land and adverse upper winds. However, the low is expected to start moving north by this afternoon, and a tropical or subtropical low is expected to form by late overnight or tomorrow when the low moves over the western Gulf of Mexico. An Air Force reserve unit reconnaissance plane is scheduled to investigate the disturbance this afternoon, if necessary.
This is the feature that will bring driving rain to the Great South this weekend. Keep in mind that the rip current danger will be high along the Gulf Coast from tomorrow through Sunday, and coastal flooding is possible.
The rest of the Atlantic basin is calm.
AT THIS DATE IN 1946: The third deadliest tornado in Canadian history struck southwestern Ontario from Windsor to Tecumseh. 17 people were killed and hundreds injured. The damage was conservatively estimated at $ 1.5 million.
