A Few Strong Storms

Afternoon thunderstorms will once again be possible today, this time as a cold front approaches the region from the north.

With the approaching front and little to inhibit thunderstorm development, the activity should start to pop up earlier today than during the last couple days. Sun and clouds this morning will start to produce showers and storms by the midday hours, if not the late morning.

On and off showers and storms will then be possible well into the afternoon, with a gradual shift south in the main areas of activity.

Conditions are bit more favorable for storm organization and damaging winds than over the last couple days. The localized severe weather Monday and Tuesday were more a product of all of the heat and humidity available to storms.

The end result may look very similar though, with a few areas of tree damage. A more widespread event like last Monday is not as likely, and the hail and tornado threats are very low. Wind and pockets of heavy rain will be the primary concern.

Temperatures will make it to the low 80s late this morning before the storm activity begins. An overall cooling into the upper 70s will take place this afternoon, though it will be at least partially dependent on the storm locations.

Thunderstorms will taper off to some showers for the later afternoon and evening hours. Temperatures will slide into the upper 60s as the front progresses through the region. However, low pressure will develop along the front, and rain will increase again after midnight, mainly for the southern half of the region.

4th of July Weekend Weather

The front will stall out and hang in the area into the holiday weekend, making the forecast a bit uncertain and tricky.

Thursday will continue where tonight leaves off, with morning rain showers especially in the southern half of the region. Through the afternoon, the rain should become more scattered. High temperatures will be in just the low 70s.

Another low will pass to the south on Friday, leading to an increase in rain chances across the region. Some thundery downpours could develop within this area of rain and be slow moving. If this actually occurs, there could be a localized flood threat to consider.

With the greater chances for rain, Friday’s highs should settle in the upper 60s and low 70s.

Scattered showers will continue to be possible into Saturday. The rain does not look as heavy or widespread, so the chances for a washout of a day are much less than on Friday.

Temperatures will remain cool, with another day of upper 60s and low 70s.

The driest day of the Holiday weekend looks to be on Sunday, the 4th itself. A stray shower cannot be ruled out, especially in the eastern regions, but most areas should be rain-free. Highs will respond by reaching the mid and upper 70s.

Unsettled weather looks like it will move back in for at least the first part of next week. Temperatures may get back into the 80s for a couple days as well.
