Record Setting Average Temperatures for March 2012

Although spring began officially on March 20th, it seems like summer is already well under way across north and central Georgia! The warm temperatures throughout March were reflected at all of our four climate stations, with three of the climate stations (Athens, Atlanta, and Columbus) all reporting the warmest average temperature on record for the month of March. These above average temperatures can, for the most part, be attributed to the ridge of high pressure that dominated across the area during the month. More information can be found in the table below on the average temperature in 2012 compared to previous years.

  Very much needed over the right areas.



This is turning out to be a really cool summer so far. (Pun and No Pun intended.)

TWC's forecast has the coolest forecasted temps out of anyone right now.

YIKES!!!! 18z GFS, The GFS has been showing this on all the runs today, this is the hottest run yet! It has me getting to a high of 104 next Monday (July 2nd)!

HEATWAVE ALERT: TRIPLE DIGIT HEAT POSSIBLE FOR NORTH GEORGIA; RECORD HIGHS IN JEOPARDY

TIMELINE: THU-MON (JUNE 28 - JULY 2)
FIRST TRIPLE DIGIT HEAT POSSIBLE FOR ATLANTA SINCE AUGUST 2007!

The GFS/CMC/ECMWF are in good agreement of the HOTTEST temperatures so far this summer moving into our area beginning later this week into the weekend. I'm posting the 00z GFS as examples of some of the temperatures we could experience.

TWC loves to tease us. They might as well just put 100 in the forecast during that period and get it out of the way. (Attachment below)

[toxictwister00]

It is looking more and more likely we will see our first 100 degree day in nearly 5 years come this Friday. Weather outlets such as Accuweather, Wunderground, and even TWC itself have introduced at least a day or more of 100 degree heat. I specifically point out Friday because we have the potential to not only break one record, but two all in the same day!

Believe it or not, there is still a chance to tie or break records up to Independence Day.

Keep in mind that the reason why Wunderground's forecast might be crazy and unbelievable is because what it does is it takes data from that weather station, whether a PWS or a airport, and sees what it reported in a similar event. For example, lets say there was a 101F heatwave last year. Now you guys have a similar situation coming up. So it takes the data from that last heatwave and says, well, that station reported 107F compared to the forecast of only 101F. So now that forecasts are calling for temperatures near 100F, you will then see forecasts from WU of about 107F,108F etc.

Thanks for explaining that to me. I looked at the 12z GFS not too long ago and honestly taken for verbatim those temps WU is forecasting is similar to that run. It shows us around 104/105 but not this weekend, rather early next week.

After my last post, our NWS office finally updated their forecast to include 100 degree temperatures for this weekend. This update occurred during their afternoon package update. I know this isn't as big of a deal as I'm making it out to be, but I'm very bothered that our NWS office doesn't seem to want to issue Heat Advisories Friday and Saturday just because the heat index may not be at or above 105. If the GFS/ECMWF/NAM come close to verifying it won't matter because that 105 will turn out to be our air temperature! I don't get why they can't make an exception to this given the situation, they also mentioned about the criteria of nighttime lows falling below 75 for Thursday/Friday so that's why they aren't issuing them for those days. Given their forecast for Saturday/Sunday I don't see why they wouldn't issue Heat Advisories, but whatever.

Saturday: Sunny and hot, with a high near 100.

Saturday Night: Mostly clear, with a low around 75.

Sunday: Mostly sunny and hot, with a high near 100.

Sunday Night: Partly cloudy, with a low around 75.
