Hurricane “Delta” is currently a category 3 “major” hurricane on its way for a landfall in southwestern Louisiana early this evening. There is a chance for some weakening of Hurricane “Delta” in the last few hours before landfall – perhaps from a category 3 to a category 2 storm – as it will push over cooler waters of the northern Gulf of Mexico. After landfall, Hurricane “Delta” will weaken quickly; however, its remnants will bring some significant rainfall to the Deep South, Tennessee Valley and as far north and east as the Mid-Atlantic region from Sunday into Monday.

High pressure to our north will control the weather around here again today providing us with another day of sunshine and comfortable temperatures. In fact, this same high pressure system will hang on for the first day of the weekend, but then attention will turn to our southwest where the moisture field associated with the remains of Hurricane “Delta” will be pushing in our direction. Hurricane “Delta” is likely to make landfall late today in the southwestern part of Louisiana which is the same area that experienced a direct hit by Hurricane ‘Laura” back in mid-August. After Hurricane “Delta” makes landfall, it will weaken quickly and become increasingly influenced by a developing mid-level trough over the south-central US which should cause it to turn to the northeast and this will result in significant rainfall across the Deep South and Tennessee Valley. By the latter part of the weekend, the remains of Hurricane “Delta” are likely to result in a decent rainfall for the DC-to-Philly-to-NYC corridor.

Hurricane “Delta” pounded the northeastern part of Mexico’s Yucatan Peninsula yesterday morning and its encounter with the land mass weakened the tropical cyclone from a category 4 “major” storm to a category 1. Since then, Hurricane “Delta” has moved out over the warm waters of the southern Gulf of Mexico into an area with more favorable atmospheric conditions and has re-intensified into category 2 status with maximum sustained winds of 105 mph. In this favorable environment with low vertical wind shear and deep moisture, Hurricane “Delta” could return to “major” hurricane status (i.e., category 3 or higher) as it churns towards a likely landfall late Friday in the southwestern part of Louisiana. After landfall, Hurricane “Delta” will weaken quickly, but its remnants will bring some significant rainfall to the Deep South, Tennessee Valley and as far north and east as the Mid-Atlantic region by the Sunday/Monday time frame.

A cold front passed through the region and it ushered in a cooler air mass for the Mid-Atlantic as high pressure build to our northwest. This same high pressure system will control our weather through the first half of the weekend, but then attention turns to our southwest where moisture will be pushing towards us associated with the remains of Hurricane “Delta”. The remnants of “Delta” could produce rainfall around here from Sunday into Monday and then a strong frontal system could produce additional rain around here by the middle of next week.

Hurricane “Delta” pounded the northeastern part of Mexico’s Yucatan Peninsula this morning as a category 2 storm and is now entering the southern part of the Gulf of Mexico. After its bump into with the Yucatan Peninsula, Hurricane “Delta” will encounter favorable conditions for intensification as it churns northwest over the still warm waters of the southern Gulf of Mexico in an environment with low wind shear and high moisture content. As such, Hurricane “Delta” is likely to re-intensify into “major” hurricane status as it heads on a path towards the north-central Gulf coast - and perhaps right to the same region that experienced the landfall of Hurricane Laura earlier this tropical season. After landfall likely on Friday, the remains of Hurricane “Delta” are then likely to push to the north and east bringing significant rainfall to the Deep South, Tennessee Valley and perhaps to the Mid-Atlantic region late in the upcoming weekend.

High pressure will control the weather again today providing us with plenty of sunshine a warmer conditions compared to Tuesday. Strong low pressure will pass by well to our northwest later in the day and drag a cool front through the area ushering in cooler air for the next couple of days. High pressure will then resume control at the end of the week and for the beginning part of the weekend – after that, attention will turn to the southern states. Hurricane “Delta” has rapidly intensified during the past couple of days and may have a direct impact on the north-central Gulf coastal region by the early part of the weekend. Once inland, the remnants of Hurricane “Delta” are likely to run to the north and east bringing significant rainfall to the Deep South and Tennessee Valley. In fact, the remains of “Delta” could result in some rainfall around here by the late stages of the upcoming weekend.

All systems are go for Hurricane “Delta” as it has undergone rapid intensification in the last 24 hours and will very likely reach at least category 4 “major” hurricane status over the next 12-24 hours. During the past 24 hours, Hurricane “Delta” has seen its maximum sustained winds increase by 70 mph – now at 110 mph – which represents the fastest October intensification of a tropical cyclone since “Wilma” of 2005. Hurricane “Delta” is headed towards the northeast part of the Yucatan Peninsula region of Mexico in coming days – very likely as a category 4+ storm. After that, “Delta” may make a direct impact on the north-central Gulf coastal region (e.g., southern Louisiana) by late Friday or so and then take a turn to the north and east once inland with significant rainfall in the Deep South and Tennessee Valley – perhaps even bringing some late weekend rainfall to the Mid-Atlantic region.

High pressure will build into the area today providing us with another nice day featuring comfortable temperatures and plenty of sunshine. Strong low pressure will pass by well to our northwest on Wednesday and drag a cool front through the area ushering in cooler air for the latter part of the week. High pressure will resume control at the end of the week and for the beginning part of the weekend and then attention will turn to the Deep South. Hurricane “Delta” is now a category 2 storm and could reach “major” hurricane status during the next couple of days. Hurricane “Delta” could have a direct impact the northern Gulf region (e.g., Louisiana) by late Friday or so and then its remnants may result in rainfall for the Mid-Atlantic region by the end of the weekend.

A cold frontal system is clearing the coastal region this morning and a cool air mass for early October will spread east to the Mid-Atlantic from the Great Lakes. In fact, it’ll stay cooler-than-normal right through the upcoming weekend with highs confined to the 60’s on each day. Low pressure may try to form along the east later Sunday night and Monday and it could result in shower activity as we begin the new week. As the central and eastern states experience a chill down this weekend, the western states will get hotter and stay rain-free and this will increase the threat for wildfires in that part of the nation.

Just 100 miles up the coast from where the Wright brothers first flew their airplane at Kitty Hawk, North Carolina, Northrop Grumman is scheduled to launch its Cygnus cargo spacecraft aboard the Antares rocket from the Mid-Atlantic Regional Spaceport (MARS), located at NASA’s Wallops Flight Facility in Virginia. The rocket launch is scheduled for 9:38 PM Thursday, October 1st at NASA’s Wallops Island Facility and it may be visible throughout the Mid-Atlantic region (launch was originally scheduled for Tuesday, but was scrubbed due to rainy weather conditions).
