Stormy weather pattern begins Thursday
A stalled front brings more storms to end the week.
A front will stall out over our area through the weekend allowing for daily chances of showers and storms. A ripple of energy will swing along the front Thursday increasing our chances of storms. While the front won’t necessarily bring “cold” air, it will drop temperatures to a more seasonable level. It will likely break our streak of 90 degree days by Friday. Another low pressure system will ride along the front keeping a chance of showers and storms going into the weekend. We’ll also continue to monitor the potential Tropical Storm Isaias. This could affect the U.S. as early as this weekend.
Any storms should taper off during the evening hours. Partly cloudy skies are expected overnight with some areas of patchy fog. It will be a muggy night with lows in the mid 60s to low 70s.
THURSDAY & FRIDAY
With the front stalled nearby, this will allow for better storm chances over the next couple of days. A disturbance will enhance the coverage of storms Thursday afternoon with numerous showers and storms expected to develop by lunch time. With heavy rain anticipated, flooding will be a possibility. Severe weather is not as likely, but we can not rule our a few strong to severe storms. We will continue with likely storm chances again on Friday with some activity even possible as early as the morning. Highs will likely drop back into the mid to upper 80s area-wide by Friday. Roanoke may still hit 90 on Thursday, but it will be close. depending on the timing of storms.
We’ll continue to see a mix of sun and clouds through the weekend with highs holding in the mid to upper 80s. Scattered showers and thunderstorms will also be likely each afternoon.
The National Hurricane Center is expecting Tropical Cyclone 9 to develop into a Tropical Storm Isaias (ees-ah-EE-ahs) sometime Wednesday night. This will be a system to watch as the forecast path brings the storm near Florida by this weekend. This forecast track will change over the coming days, but any landfall in the Southeast could bring tropical moisture to our region. The latest modeling suggests tropical moisture early in the week which would further increase our storm chances.
