Hot Days, With Scattered Storms… Watching Tropics… Wednesday Update – 4:18pm

Warnings_242

Good Wednesday afternoon! Some drier air has moved into central and west Alabama today, which has been noticed by the slightly lower humidity. Dewpoints are generally in the middle 60s across our area. Dewpoints were in the 70s yesterday. While that’s not much of a change, it is enough to keep the rain south of our area. Notice the radar image as of 4:10pm Wednesday. Scattered storms were moving across much of south Alabama, just on the south side of a stationary front. Humidity is much higher just south of that boundary… The front will gradually move back to the north on Thursday and Friday, which will cause humidity to increase. We’ll also notice an increase in scattered storms for the rest of the week and into the weekend. All of our area will stay dry this afternoon, evening and tonight.

The forecast starts to change a bit on Thursday and Friday, as the risk of scattered afternoon storms return to the forecast. Highs will top out in the lower 90s on Thursday and Friday, with a 20% chance of afternoon storms. I think most areas will stay dry on Thursday and Friday, but don’t be shocked if you get a 20 to 30 minute downpour at your house.

As moisture levels increase a bit, the risk of afternoon storms will also increase. While I don’t expect a big rain event over the entire area, a few scattered storms will be possible over the weekend and into early next week between lunch and 8pm. The risk of rain is very low during the morning and overnight hours, due to the loss of afternoon heating. The weather over the weekend and early next week will be very typical of a summer pattern. Rain chances remain at 30% each day, with a high near 90 and a low near 70.

Tropical Storm Barry has formed in the southwest Gulf of Mexico this afternoon, with winds of 40mph. There is no chance this system will impact our local weather; in-fact, the storm will move into Mexico tonight or early Thursday, with heavy rain and storms in that area. There are no other areas we’re watching in the tropics at this time…

Tropical Storm Barry Forms in the Gulf… Tropical Update – 4pm Wednesday

Warnings_241

Good Wednesday afternoon! We’ve got another tropical storm in the Gulf of Mexico, but there are no worries with this storm reaching Alabama’s coast. Barry will move into central Mexico later tonight or very early Thursday. Here’s the discussion from the National Hurricane Center:

SATELLITE IMAGERY AND DATA FROM AN AIR FORCE RECONNAISSANCE PLANE INDICATE THAT THE TROPICAL DEPRESSION IN THE SOUTHERN BAY OF CAMPECHE STRENGTHENED AND IS NOW TROPICAL STORM BARRY…THE SECOND NAMED CYCLONE OF THE 2013 SEASON.  SFMR AND FLIGHT-LEVEL WINDS FROM THE AIRCRAFT YIELD AN INITIAL INTENSITY OF 35 KNOTS. SOME SFMR VALUES WERE A LITTLE HIGHER…BUT THESE WINDS WERE RAIN CONTAMINATED AND WERE DISCARDED. THERE IS A CHANCE FOR BARRY TO STRENGTHEN SLIGHTLY JUST BEFORE LANDFALL DURING THE NEXT 12 TO 18 HOURS. RAPID WEAKENING IS ANTICIPATED AFTER THE CENTER MOVES INLAND…BUT RAINS WILL CONTINUE.

 BARRY HAS BEEN MOVING WESTWARD ABOUT 5 TO 10 KNOTS DURING THE DAY… AND THIS GENERAL MOTION  WITH A DECREASE IN FORWARS SPEED IS FORECAST TO CONTINUE UNTIL LANDFALL. ONCE INLAND…AND THE CENTER BECOMES DISRUPTED BY THE HIGH TERRAIN…THE REMNANT CIRCULATION WILL LIKELY CONTINUE WESTWARD OVER THE STATE OF VERACRUZ UNTIL DISSIPATION. GLOBAL MODELS HAVE A NARROW RIDGE OF HIGH PRESSURE OVER THE NORTHERN GULF OF MEXICO…AND THIS FLOW PATTERN IS CONSISTENT WITH THE FORECAST WESTWARD MOTION OF THE TROPICAL STORM.

 IT IS IMPORTANT TO EMPHASIZE THAT REGARDLESS OF THE EXACT TRACK AND WHETHER THE CYCLONE STRENGTHENS…THE MAIN THREAT WILL BE HEAVY RAINFALL…WHICH COULD CAUSE SIGNIFICANT FLOODING OVER A LARGE PORTION OF SOUTHERN MEXICO PRIMARILY IN THE STATE OF VERACRUZ DURING THE NEXT COUPLE OF DAYS. SO PLEASE DO NOT FOCUS ON THE EXACT CENTER LOCATION OF THE CYCLONE.
