All eyes are now on the tropics now as soon-to-be Hurricane Michael is heading to the open Gulf of Mexico and it could very well reach "major" hurricane status before making landfall at mid-week. The overall upper-level pattern (i.e., very strong ridging centered over SE Canada/NE US) is one that opened the door for tropical activity in the Caribbean Sea and Gulf of Mexico and indeed, this system had its origins last week in the southwestern Caribbean Sea and will now move northward over the warm waters of the Gulf of Mexico. Once Michael makes landfall, it is likely to turn from the north to the northeast and should ride up along the Southeast US coastline as it interacts with a frontal system. There is the high potential for heavy rainfall from Michael in places like North and South Carolina – where they certainly don’t need any – and even a chance it’ll impact the Mid-Atlantic region later in the week. It’ll turn colder for awhile behind the passage of this tropical system as some Canadian chill that has been bottled up to our north finally makes its way into the eastern US.

Upper-level high pressure ridging continues to be situated over the eastern US resulting in very warm and generally dry conditions here in the Tennessee Valley. This ridge of high pressure will intensify over the next few days over the southeastern part of Canada and this opens the door for tropical activity in the Gulf of Mexico, Caribbean Sea or southwestern Atlantic to potentially reach the southeastern US. In fact, there is currently a tropical disturbance located in the southwestern part of the Caribbean Sea and it is still a little too early to tell if it will spill out over the Gulf of Mexico and possibly have an impact in the Southeast US.

Upper-level high pressure ridging will build strongly later this weekend across southeastern Canada and this always raises a red flag this time of year for the potential of tropical systems to “slide underneath” the ridge and head towards the SE US. As a result, we’ll keep a close eye on the Caribbean Sea, southwestern Atlantic and Gulf of Mexico during the next couple of weeks for the potential of east-to-west moving tropical activity.

High pressure ridging at upper levels of the atmosphere will build strongly over the weekend and well into next week across the NE US and SE Canada and this always raises a red flag this time of year for potential tropical systems to “slide underneath”. As a result, a close eye will need to be kept on the Caribbean Sea, southwestern Atlantic and Gulf of Mexico during the next couple of weeks for the potential of east-to-west moving tropical activity.

Southwesterly flow continues to dominate the scene around here as high pressure ridging extends westward into the area from the western Atlantic Ocean. As a result, quite warm and humid air has pushed into the region and this will continue the chance for showers and thunderstorms in the Tennessee Valley on this Tuesday. Slightly drier air later this week in the upper atmosphere may reduce chances for rain somewhat across the Tennessee Valley and this may also result in slightly higher temperatures closer to the 90 degree mark for afternoon highs.

Southwesterly flow will dominate the scene around here over the next few days as high pressure ridging extends westward into the area from the western Atlantic Ocean. As a result, quite warm and humid air will push into the region and this will raise the chance for daily showers and thunderstorms for the next couple of days. Slightly drier air later this week in the upper atmosphere may reduce chances for rain somewhat across the Tennessee Valley and this may also result in slightly higher temperatures closer to the 90 degree mark for afternoon highs.

Slightly cooler and drier air should push into the region today as we end the work week and our chances for rain will diminish. Temperatures should be rather pleasant for this time of year with highs this afternoon not far from the 80 degree mark. As high pressure builds across the Southeast US this weekend, moisture will make a return to the Tennessee Valley and shower/thunderstorm chances will be on the increase as we reach the early part of next week.

A frontal system will slowly push through the area today and continue our chances around here for showers and thunderstorms. Any rain that falls today can result in localized flooding issues given the well saturated grounds following recent rainfall. This same frontal system will push back to the north on Friday and this will extend our chances for showers and thunderstorms in the Tennessee Valley.

A frontal system will slide towards the region today and bring with it a good chance for additional showers and thunderstorms. Any rain that falls today can be on the heavy side given the high humidity levels that currently exist in the area. The front will be rather slow to move through the region; consequently, there may be more shower and thunderstorms to deal with on Thursday as well. In fact, flash flooding may become an increasing concern on Thursday given the recent rainfall in this part of the Tennessee Valley.

A wet pattern continues here today with thunderstorms becoming more numerous in coverage by the afternoon and showers are likely tonight as well. The threat for showers and storms will continue on Wednesday, but then drier air is likely to arrive by Thursday following a frontal passage. The unsettled pattern returns for the late week and weekend.
