From bad to good weather

There is light at the end of the prolonged wet and/or cloudy spell we have been going through. As I’ve been advertising on the radio for a few days now a prolonged dry spell is expected to begin Sunday and last through next Thursday, with modest thunderstorm chances returning Friday and next weekend. By the way, from this long distance, 4th of July weather looks pretty typical for the Metro, very warm and humid with around a 30% chance of an afternoon or evening thunderstorm.

But first things first. We are still in a warm very deep moist tropical air mass. And while we get to see some sun today and tomorrow, we are not done with rain just yet, nor the threat of an isolated severe storm or small, weak tornado. Listen for details on the weather today this weekend and next 5 days on the radio in my reports for updates.

Due to the tropical nature of the air in place, more heavy downpours are likely in spots late today and overnight into tomorrow and that’s on already saturated soils, so a FLASH FLOOD WATCH has been issued for all of Metro Atlanta north of Griffin. Take note that trees may fall in the wet root zones without new rain or without high wind.

Also bear in mind that in tropical systems lightning and thunder is often at a minimum, even in storms capable of producing damaging straight line winds or a tornado, so you may get little or no warning.

You can see what’s left of Tropical Storm Cindy and the approach of a front from the north.

The remnants of Cindy will push eastward, and interact with shear
axis/weak convergence boundary through Saturday. This shear
axis/weak convergence zone will slowly sag south across the metro area
through Saturday, serving to focus areas of precipitation.

As with any tropical system, the potential for severe weather will
exist. Especially for isolated tornadoes within any rain-bands. Areas
roughly along and west of the Interstate 85 corridor will have the
best potential for any severe weather through tonight. However, if
good heating occurs across southern areas today, an isolated
severe thunderstorm is not out of the question there, too.

A welcome change is headed our way in the long term as drier air
moves into the region, with lower than normal temperatures continuing and lower than normal humidity moving in with a less than normal rain odds Sunday through next Thursday.
