Blue Ridge Posted April 27, 2011 Share Posted April 27, 2011 The damage this morning from that weakening line of storms was impressive over northwest ga...countless trees down. Definitely. I have a friend attending Berry College in Rome, and many there were forced into basements as the line passed. Many, many trees were downed on campus (sad, considering how beautiful of a school it is). She is still without power >4 hours later. Link to comment Share on other sites More sharing options...
Blue Ridge Posted April 27, 2011 Share Posted April 27, 2011 Sun is beginning to peak through in Northeast Tennessee. Temperatures and dew points are amping up across all of East Tennessee as the sky clears. Going to be a long, long day across the Southeast. Wind is already gusting over 30 MPH in Knoxville and the Tri-Cities. Link to comment Share on other sites More sharing options...

CandymanColumbusGA Posted April 27, 2011 Share Posted April 27, 2011 45% probs of tornadoes. I saw that.... I cannot recall the last time I saw tornado probabilities that high before... This is going to be a pretty ugly situation... First you had the storms knock hundereds if not thousands of trees over this morning in West Alabama... Second, those storms took a lot of power lines down (I head at least 250K without power this morning at some point). Third, if you don't have power NOR a weather radio, how are you going to get weather information reliably? Phones, I hope?? Fourth, the amount of heating we are seeing all across Alabama and Georgia... Temperatures are easily pushing low to mid 80s for many of us and there is still a long ways to go until sunset... Fifth, the moisture feed from the Gulf is ridiculous! I'm seeing spotty sprinkles pop up on radar well ahead of the main action in Mississippi... Needless to say, I am VERY worried about the severity of this outbreak. I have a feeling it's going to get pretty rough for my viewing area and it's going to be an extremely long night...

DaculaWeather Posted April 27, 2011 Share Posted April 27, 2011 Huntsville Update HYDROLOGY...SIGNIFICANT RIVER FLOOD EVENT POTENTIALLY UNFOLDING ACROSS THE TN VALLEY TODAY. RAINFALL AMOUNTS OF 2 TO 3 INCHES HAS ALREADY FALLEN OVER THE LAST 36 HOURS ACROSS THE NW ALABAMA AND SRN TN INCLUDING THE IRON CITY AND BIG NANCE BASINS. AMOUNTS SO FAR HAVE BEEN LESS EAST OF I-65 WITH 1 TO LOCALLY 2 INCHES. WITH SEVERAL ROUNDS OF ROBUST CONVECTION EXPECTED AHEAD OF THE LATE EVENING FROPA...RAINFALL TOTALS OF 4 TO 5 INCHES SEEM LIKELY IN THE IMPACTED BASINS. LATEST GUIDANCE INDICATES THAT MODERATE FLOODING IS EXPECTED ALONG THE PAINT ROCK AND ELK RIVERS WITH MAJOR FLOODING ALONG THE BIG NANCE NEAR COURTLAND. IN FACT...THE RIVER STAGE AT COURTLAND IS FORECAST TO RISE TO 23 FEET BY THURSDAY MORNING. THIS WOULD BE THE HIGHEST CREST THERE SINCE 1990 AND WOULD CAUSE SIGNIFICANT IMPACTS IN AND NEAR COURTLAND.

FoothillsNC Posted April 27, 2011 Share Posted April 27, 2011 lots of sun and muggy dewpoints ahead of the main front. Alabama, TN and western and northern GA are in for it pretty soon. This is a very serious situation, I hope all of our posters in that area have a plan in case this potential comes to reality. The tops of Anvils in western MS look like they're over 50K feet already. No doubt we're on the cusp of a historic, memorable weather event. Link to comment Share on other sites More sharing options...

audioguy3107 Posted April 27, 2011 Share Posted April 27, 2011 Temp at 80 dewpoint getting closer to 70. I can't remember the last severe weather "event" such as this where we had temps in the 80s and DP that high. This is not a good situation.

Amos83 Posted April 27, 2011 Share Posted April 27, 2011 just had the SVR Tstorm roll through my office here in Davidson. Nothing of any significance except for a few claps of thunder and 10 minuts of moderate rain. Sun is already back out..... looks like the SE is pumped and primed for an historic event. My prayers are will everyone down in GA, TN, and AL. I've already called my Grandma in Smyrna, GA to make sure she stays alert . It's going to get ugly soon.

Hopefully she is safe and everyone else is too. I'd love nothing more than for there to be no fatalities today. Realistically, I don't know if that's possible though.

Lookout Posted April 27, 2011 Share Posted April 27, 2011 lol.... I agree though it's gonna be bad, I bet we get some discrete cells. I wondered if anyone was going to catch that I have little doubt at this point given the developing cumulus field and strong surface heating. I'm betting there are going to be some monster supercells at some point, especially alabama. I saw that.... I cannot recall the last time I saw tornado probabilities that high before...

Yeah you tv guys are going to have a fun time of it later today/tonight. Cumulus development looks quite robust around your area/central/eastern alabama. SPC hasn't issued a meso discussion yet on it but I would have to think some will pop in this area pretty soon, cape is in the 2500 to 3000 range there.

kayman Posted April 27, 2011 Share Posted April 27, 2011 Some of this mini-alley may be a consequence of these counties having a higher population than others, giving more people to witness and report tornadoes and their damage. But that may not be the full explanation, as some of the adjacent counties to the east of Atlanta also have high populations. My theory is that a part of the explanation for the mini-alley may be that warm fronts often tend to stall out over the north suburbs of Atlanta, just south of the mountains of north Georgia. As was the case Saturday, tornado-spawning thunderstorms can get an extra boost of updraft strength and an extra source of rotation from the colliding winds along such fronts So if the mini-alley is the consequence of a higher population and the fact that warm fronts stall over the northern suburbs, how does that explain so many tornadoes in Carroll County ? A relatively rural county and definitely not in the northern suburbs or anywhere close to mountains. Tornadic supercells that usually come through Carroll County are ones from East Central Alabama counties like Tallapoosa, Randolph, Cleburne, and Chambers, where severe weather tends to redevelop after passing over the mountain ridges in Central Alabama.

I'm using this info to try and impress on friends of mine to the west in GA/TN that they've got to take this seriously. I must admit I was expecting it to be a severe thunderstorm watch and the parameters for tornados arent that great around this area YET Here are the offical probabilties for this watch Probability of 2 or more tornadoes Mod (40%) Probability of 1 or more strong (F2-F5) tornadoes Low (20%) Wind Probability of 10 or more severe wind events Mod (30%) Probability of 1 or more wind events > 65 knots Mod (30%) Hail Probability of 10 or more severe hail events Mod (40%) Probability of 1 or more hailstones > 2 inches Mod (30%) Combined Severe Hail/Wind Probability of 6 or more combined severe hail/wind events High (70%) Link to comment Share on other sites More sharing options...

Dunkman Posted April 27, 2011 Share Posted April 27, 2011 A couple observations so far... It's really scary to think that TW 232 has those probabilities and it only includes a small piece of the highest risk area. Storms passing over the areas in MS, AL, TN, etc. seem to be doing nothing to stabilize the atmosphere because there seems to be another line just as strong coming through 2 hours later.

Gastonwxman Posted April 27, 2011 Share Posted April 27, 2011 What a sight this system looks already, and it's only the beginning of what's down the road later today.. On another note: ... A Tornado Warning remains in effect until 100 PM CDT for extreme southeastern Madison and central Marshall counties... At 1245 PM CDT... National Weather Service Doppler radar continued to indicate a tornado. This tornado was located 8 miles northwest of Union Grove... or about 12 miles north of Arab... moving east at 50 mph. Other locations in the warning include but are not limited to New Hope... Hebron... Guntersville... Grant and Columbus City. Link to comment Share on other sites More sharing options...
VeronicaCorningstone Posted April 27, 2011 Share Posted April 27, 2011 Thunder booming just a few miles off to my west... And here comes the rain - it's pouring enough that it's hard to see the houses across the street. I really need to pick up a rain gauge; I'd love to know how much has fallen since yesterday afternoon here at the house. We had some soakers yesterday, off and on, even early this morning and it's really coming down again. Thankfully, the winds are not too bad at the moment - but with all this soaking rain, especially if it continues and the winds pick up - trees are coming down. And this neighborhood is FULL of trees. I am also not looking forward to the coming Tornado Extreme Part Deux: Electric Boogaloo. I'm worried about it here, especially after last Saturday (I am really not happy about the possibility of holing up in the closet again) but man...you guys in MS, AL, TN, and GA...I'm truly worried for you. Times like these, I really, REALLY wish I had a basement. edit: Tornado Watch just went up from RAH. I'm a little surprised. Link to comment Share on other sites More sharing options...
