The first half of the week remains somewhat unsettled with an upper-level trough hanging nearby, a continuation of moist low-level onshore flow, and a daily threat of showers. The pattern will change at mid-week with the passage of a cool frontal system that will kick the moist, maritime air mass out of here and sunshine should rule later in the week. Temperatures in general will remain on the cool side limited by an abundance of clouds and persistent onshore flow during the next few days and will return to comfortably warm levels later in the week with the return of abundant sunshine.

Hurricane Helen came ashore last night near Perry, Florida as a category 4 “major” hurricane and is now pushing through Georgia as a downgraded “tropical storm”. While the remnants of Hurricane Helene will never make it this far north, some of its tropical moisture field will combine with an upper-level low to produce occasional showers around here during the next few days and some of the rain can be heavy at times. In fact, the upper-level low will be such a slow-mover that the unsettled weather conditions in the Mid-Atlantic region will continue all the way through the first half of next week with the threat of showers on each day.

Hurricane Helene pushed ashore last night near Perry, Florida as a category 4 “major” hurricane and is now pushing through Georgia as a downgraded “tropical storm”. It will bring strong winds and heavy rain to Georgia and also to portions of Alabama on Friday and Friday night. The remnants of the hurricane will push northward through much of the day and then will be forced to turn north and west and towards the Middle Mississippi Valley region due to very strong “blocking” high pressure to the north over Canada. Excessive rainfall amounts can spread throughout much of the southern Appalachians as upsloping winds will enhance upward motion and likely result in some tremendous amounts of rainfall.

Hurricane Helene has strengthened during the past 24 hours and is now classified as a strong category 2 hurricane with maximum sustained winds of 110 mph. It should continue to intensify today as it closes in on Florida’s Gulf coast with the likelihood of reaching category 3 hurricane status featuring sustained winds of 111 mph or higher and category 4 designation is still on the table. Landfall is expected early tonight along Florida’s “Big Bend” Gulf coastal region as a “major” with a significant storm surge; especially, just to the right of the landfalling location where levels can reach 15-20 feet. With some acceleration expected later today, Helene will not have much time to weaken after landfall and, as such, it is likely to reach into southern Georgia as a hurricane during the wee hours of the morning. The lasting strength of Helene and its expected track into the Tennessee Valley assures significant impact inland to include the state of Georgia, and an especially vulnerable region is the southern Appalachian Mountains where upsloping winds can result in massive rainfall amounts of 1-2 feet and severe flash flooding.
By mid-day on Friday, the tropical system will become increasingly influenced by very strong “blocking” high pressure to the north and an upper-level trough of low pressure located in the southern Mississippi Valley. The tropical low will “rotate around” this upper-level trough of low pressure for a brief time in a pattern known to meteorologists as the “Fujiwhara effect” before it ultimately dissipates and gets absorbed by the upper-level low.

Hurricane Helene has strengthened during the past 24 hours and is now classified as a category 2 hurricane with maximum sustained winds of 100 mph. It should continue to intensify today as it closes in on Florida’s Gulf coast with the likelihood of reaching category 3 hurricane status featuring sustained winds of 111 mph or higher. Landfall is expected early tonight along Florida’s “Big Bend” Gulf coastal region – likely as a “major” – with a significant storm surge; especially, just to the right of the landfalling location where levels can reach 15-20 feet.

The lasting strength of Helene and its expected track into the Tennessee Valley assures significant impact inland to include the state of Georgia, and an especially vulnerable region is the southern Appalachian Mountains where upsloping winds can result in massive rainfall amounts of 1-2 feet and serious flash flooding.

The remainder of the week will be dry across Colorado with high pressure in control over the Rocky Mountain States. Temperatures will peak later today in the upper 80’s and then only reach the low-to-mid 80’s on Friday. The weekend is setting up to be quite nice for the end of September with comfortably warm conditions.

All eyes today on the Gulf of Mexico where Hurricane Helene will intensify as it pushes to in a north-to-northeast direction putting it on a collision course with Florida’s Gulf coast. Hurricane Helene should make landfall early tonight in the “Big Bend” region of Florida’s Gulf coast likely as a category 3 “major” storm; however, climbing to a category 4 designation is on the table.
After landfall, Hurricane Helene will initially push in a northward direction bringing its hurricane-force winds and heavy rainfall to the state of Georgia. Ultimately, the remnants of Hurricane Helene will be forced to turn north and west and towards the Middle Mississippi Valley region due to very strong “blocking” high pressure to the north over Canada. Excessive rainfall amounts can spread throughout much of the southern Appalachians as upsloping winds will enhance upward motion and likely result in some tremendous amounts of rainfall.

In the Mid-Atlantic, there is a good chance of showers today with isolated thunderstorms as a warm frontal system pushes through the region…some of the rain can come down hard at times. After that, there is a good chance that some of the tropical moisture field associated with Hurricane Helene will make it this far north for the Friday/Saturday time period. As a result, showers will be a threat as we end the work week and begin the upcoming weekend.
