Warmer temperatures have been the trend over the past few days — and the pleasant streak of weather we have experienced over the last few weeks now looks to take a brief respite as we head into the weekend and the early part of next week. Increasing humidity today, coupled with a nearby boundary and mid-level atmospheric disturbance will mean increasing clouds and the chance for showers and an isolated thunderstorm. Showers and storms haven’t been around in a while — in fact, almost two weeks (more in some spots). Today will bring isolated to scattered showers and storms throughout the area from west to east, but the main story will be the humid feeling air and presence of more clouds than sun.
The unsettled weather will continue through later tonight, but only scattered showers are expected this weekend. The main story will then be the remnants of Tropical Storm Karen, and whether they track close enough to our area up the East Coast early next week to provide tropical rains. Forecast models have diverged in solutions, with some showing tropical rains and some wind while others now shunt the remnants of the system eastward out to sea.
Karen struggling: Karen weakened overnight Thursday into Friday morning, with the center of circulation becoming exposed. Convection continued to form near the center, but the storm is struggling to organize amid some stronger shear. Some re-organization is forecast today as Karen moves north-northeastward in the warm waters of the Gulf of Mexico. Later this weekend, the system is eventually forecast to make landfall on the East-Central Gulf Coast, although forecast models continue to struggle in pinning down the exact landfall area.
October meteors on the way: The Draconid and Orionid meteor showers both peak in October, with the latter historically the better performing of the two. The Draconid’s, this year, have favorable viewing conditions with an early evening moon set. It remains to be seen if the weather will cooperate, but the Orionid shower is typically one of the more consistent each year. With Comet ISON not far down the road, some exciting times are coming up for astronomers and stargazers alike as we head deeper into Autumn and Winter.
