Still a Slim Chance For a Few Showers Tonight

Still a Slim Chance For a Few Showers Tonight

There is slim chance that some showers that are in AL this afternoon could hold together and make it into the western sections of the state by later this evening. As the showers are approaching the state they are running into a bit more moisture and instability. Most models do not have the rain, but there is a weak disturbance that I can see on water vapor that could pop a few showers later on this evening. The next chance of rain this week will be on Friday when a powerful front comes down from Canada... I will have more on that on the 6pm news.

Wednesday Forecast

After a grey, foggy start to our Wednesday we will see a Mostly Sunny afternoon as a frontal system passes through the Atlanta area.  Northwesterly winds behind the front will usher in a drier more comfortable airmass.  Moisture will begin moving back in by the end of the week with a 60% chance of showers and thunderstorms as we wrap up the work week on Friday.  This weekend we will still have a chance for showers and thunderstorms as another cold front sweeps across the state.

Atlanta Weather | Tuesday Evening

Short Term

A small lingering wave is firing up a few showers and t-storms mainly south of the metro area this evening, some could contain brief heavy rainfall. Out to the west there is a strong wave at the upper levels that is heading in this direction that could bring us a chance of rain in the morning, by the afternoon we will clear out the clouds and see highs topping out in the 80's.

Friday and the Weekend

We are looking towards the weekend where we will be seeing the chance of rain increase as a strong cold front for this time of year will move into the state. The best rain chances will be Friday afternoon and evening and some of the storms could be severe. Saturday, as of right now, looks like it will be partly cloudy with temps in the 80's.

New Tornado Data Analyzed

New Tornado Data Analyzed

Scientists from the VORTEX2 group which chases storms to be able to study and understand them better may have uncovered a new key for trying to determine which storms produce tornadoes before they actually formed. This new key piece of evidence is actually linked to something that isn't normally associated with tornadoes.....light rain. Normally supercells, the ones capable of producing tornadoes, are filled with very heavy rainfall and ice. However, as seen in the image below, taken from the VORTEX2 data, there is a ribbon-like area of light rain and small raindrops inside the thunderstorm supercell that spawned the tornado.

Storms Firing Up in Parts of Georgia This Afternoon

Tonight's Severe Chances

Storms are firing again this afternoon, but it appears that the best chances of rain and severe weather will be to our south. If you will notice below (see below) that the best instability in the state is to our south, that is also where the best moisture convergence is as well. Basically this means that the storms that will be firing up this afternoon will be mainly south of the area. The storms that do sire to our south will be severe with damaging winds the main threat...

Tomorrow Rain Chances

Potential for Additional Showers and T-Storms

Potential for Additional Showers and T-Storms

We had a couple of rounds of showers and t-storms move through this morning.  The first line started moving into west Georgia around 3:30am.  That line moved across the metro area between 4-7am.  We had a brief break, then another line of storms moved through between 7:30am and 9am.  Those clusters produced some pockets of heavy rain, lightning and some gusty winds.  We had reports of 40mph winds in parts of northwest Georgia with that second line. 

The rain that moved through gave many areas some rainfall totals of a quarter to a half inch.  We have potential for a few more showers in the afternoon hours.  The Storm Prediction Center has extended the "slight risk" area into Georgia.  This slight risk includes the metro area eastward.  It's in this area where we could see a few thunderstorms that get to "severe" criteria. The main threats would be lightning, heavy rain and strong winds. 

Heavy Rain Update | 7:15pm Update

Heavy Rain Update | 7:15pm Update

Heavy rain has been moving out of the metro area this evening and will continue to head east at around 30mph. Just under 0.50" or rain fell at the airport, but they actually had a ground stop for a while there for the heavy t-storms that were moving in. This area of heavy rain is now all east of 75 and it will continue to clear the metro aounties over the next hour. We are watching an area of severe weather out in northern Mississippi tonight that is trying to head in this direction for tomorrow, I will ahve another update on the blog about that area later this evevning.
