Lookout Posted April 6, 2011 Share Posted April 6, 2011 glad i didnt plant anything yet! was 31.2 when i took the dog out this morning. a decent frost as well - still visible in the shady areas at 9 am 31.7 here this morning with a light frost. Donalds sc across the river reported 29 so low lying areas were probably colder. Hopefully this is the last one. But it was absolutely gorgoues today..the bright blue sky, bright sun, the best looking green grass I've seen in a while, and the new leaves on the trees made for a spectacular looking day. Does not get any prettier than it was today. Yep looks like nothing but boredom for awhile. No chance to make up for the severe fail anytime soon . I hate these long boring periods. Imagine months on end of it though. I don't know how people out in the southwest stand it. I know they might have some interesting and fun weather some times of the year but the long stretches of no weather to speak of except heat would make me go nuts.

Welcome to my life. Since I moved away to the San Francisco Bay Area from Durham in November 2009, I haven't made more than literally a handful of weather-related posts (<---- see post count compared to the thousands I had on easternus) . It really sucks to have a hobby killed like that. Will be visiting the Triangle for the next few days, though. Just in time to have back-door coldfront issues and the entire realm of excitement being strictly a temperature/cloudcover forecast. Link to comment Share on other sites More sharing options...

Gastonwxman Posted April 7, 2011 Share Posted April 7, 2011 It looks like the backdoor front that's expected to drop in for the weekend will aid in some thunderstorm development across NC and SC. Before, it didn't seem like it would do much but now given the setup aloft suggested by some of the modeling (the 0z NAM in particular), including the increased moisture level, some good lifting, and tapping into daytime heating, we could actually get in on some decent convection. We will need to watch how the short wave back west behaves as it departs from the Plains and heads eastward. A correct timing on its part can really assist with producing more storms in a widespread fashion. If what SPC says about our instability and bulk shear verifies, some severe weather is possible during the late afternoon/evening period. It will all depend on the timing and strength of the cold front but this has now got my interest. Link to comment Share on other sites More sharing options...

MountainMarvel Posted April 8, 2011 Share Posted April 8, 2011 no frost but 32 here this morning. I think most of us outside the mountains are now done with frost until next October or November. No cold air showing up in any model runs, but atleast we get 2 more weak fronts next week each with a little bit of rain. Also, there's no huge outrageous heatwaves yet, ie, 588dm ridges in the Southeast. I'm going to enjoy the warmer, sunny weather. I've had ice on the cars four of the first seven mornings of April. Low was 29 yesterday, 33 this morning. Last year, my last morning with ice was May 10th. That means four more weeks before the coast is clear..... Being from Miami, I don't mind a bit. Here are two pics from Lake Lure on Sunday, and one from this frosty morning. Heaven on Earth. Link to comment Share on other sites More sharing options...

UNCCmetgrad Posted April 8, 2011 Share Posted April 8, 2011 Looks like I will be chasing on Saturday afternoon toward SC if storms fire up. Looks like that will be your best bet. I'm wondering how much instability will materialize in NC?. The NAM has been hinting at a lot of cloudiness Saturday with even a very shallow wedge showing up and handing around most of the day with northeast winds in the lowest layers. I believe the NAM pushes the backdoor front further south than the other models, but these fronts can often make it further south than predicted. Good luck and good chasing!

Thank you and yes the wedge boundary will have to be watched. We will have to see if any storms can fire and cross the front which always enhances the TOR risk.

Gastonwxman Posted April 8, 2011 Share Posted April 8, 2011 Could be some super cell development if everything comes together correctly for a few folks. The deep layer and directional shear looks impressive and high lapse rates look sufficient to cause some of the severe cells that do develop to cause some nasty wind damage to occur. Don't know if it would be on par with the past event but it bears watching. Link to comment Share on other sites More sharing options...

A STRONG UPPER TROUGH IS FORECAST TO DIG ACROSS CA TODAY...WHILE WEAK UPPER RIDGING TAKES PLACE OVER MOST AREAS EAST OF THE ROCKIES. DESPITE THE RIDGING ALOFT...RATHER STRONG WESTERLY MID LEVEL FLOW AND INCREASING INSTABILITY WILL RESULT IN A RISK OF SEVERE THUNDERSTORMS OVER SEVERAL AREAS TODAY. AT THE SURFACE A FRONTAL BOUNDARY FROM NRN NC EXTENDS NWWD ACROSS APPALACHIANS THRU WRN WV AND THEN WWD TO N OF OH RIVER...THEN WSWWD ACROSS CENTRAL MO TO SWRN KS/OK BORDER. THIS BOUNDARY SEPARATES THE LARGE WARM SECTOR TO THE S WHICH IS UNDERGOING DESTABILIZATION FROM BOTH THE PRESENCE OF AN EML AND ADVECTION OF GULF MOISTURE...AND A COOLER AIR MASS TO THE N. ...OH/TN VALLEYS TO WRN CAROLINAS... RAPID DESTABILIZATION IS TAKING PLACE EWD ACROSS KY/TN TO S OF FRONTAL BOUNDARY WITH DEWPOINTS RISING INTO THE MID 60S. STRONG HEATING IS OCCURRING THIS AM OVER LOWER OH VALLEY AND WILL LEAD TO A MDTLY UNSTABLE...WEAKLY CAPPED AIR MASS BY EARLY THIS AFTERNOON. MLCAPES AOA 2000 J/KG COUPLED WITH BRN SHEAR OF 50-60KT WILL PROVIDE A FAVORABLE SEVERE THUNDERSTORM ENVIRONMENT PARTICULARLY FOR LARGE HAIL GIVEN THE STEEP MID LEVEL LAPSE RATES. STORMS SHOULD INITIATE VICINITY/S OF THE FRONTAL ZONE NEAR OH RIVER BY EARLY/MID AFTERNOON AND THEN QUICKLY EVOLVE INTO LINE SEGMENTS/BOWS AS WELL AS POSSIBLE SUPERCELLS. VERY LARGE HAIL WOULD BE POSSIBLE ASSOCIATED WITH ANY SUPERCELL GIVEN THE EXPECTED ENVIRONMENT ALONG WITH ISOLATED TORNADOES. HAVE INCREASED BOTH WIND/HAIL PROBS WITH THE POTENTIAL FOR EVEN A HIGHER RISK OF WIND IF STORMS EVOLVE INTO LINE SEGMENTS AND BOWS. ADDITIONALLY HAVE SPREAD THE SLIGHT RISK INTO THE WESTERN CAROLINAS AS IT NOW APPEARS SUFFICIENT INSTABILITY WILL BE PRESENT TO MAINTAIN AN ORGANIZED THREAT GIVEN THE PRESENCE OF 40-50 KT OF SHEAR. ...OK/KS INTO MID MS AND OH VALLEYS THIS EVENING... SURFACE BOUNDARY EXTENDING FROM NEAR THE OK/KS BORDER EASTWARD INTO MO/IL WILL LIKELY BE FOCUS OF SEVERE THUNDERSTORM DEVELOPMENT. OPERATIONAL AND EXPERIMENTAL MODEL SOLUTIONS CONTINUE TO SUPPORT THE DEVELOPMENT OF ISOLATED THUNDERSTORMS BY LATE THIS AFTERNOON OVER NORTHERN OK AND SOUTHEAST KS DESPITE WEAK FORCING ALOFT. STRONG HEATING AND INCREASING MOISTURE WILL HELP TO REDUCE CAP AND AID IN INITIATION. WITH MLCAPES RISING TO 3000 J/KG SUPERCELL STORMS WILL BE LIKELY WITH LARGE HAIL AND DAMAGING WINDS POSSIBLE. THE ACTIVITY IS EXPECTED TO INCREASE IN COVERAGE AS IT SPREADS EASTWARD ALONG THE BOUNDARY INTO THE MID MS VALLEY...AND EVENTUALLY INTO THE OH VALLEY AFTER MIDNIGHT. DAMAGING WINDS WILL LIKELY BE THE MAIN THREAT...ALTHOUGH LARGE HAIL WILL REMAIN POSSIBLE. IF SUPERCELL STRUCTURES CAN BE SUSTAINED IT WILL INCREASE THE POTENTIAL FOR TORNADOES AND VERY LARGE HAIL. EXPECTED COVERAGE PRECLUDES THE INCREASING LOWER RISK COVERAGE PROBABILITIES ATTM. ...GULF COAST STATES... AMPLE LOW LEVEL MOISTURE HAS RETURNED TO THE GULF COAST REGION THIS MORNING WITH MID/UPR 60 DEWPOINTS AS FAR NORTH AS TN. WIDESPREAD LOW CLOUDS ARE RETARDING THE HEATING THIS MORNING. HOWEVER...CINH WILL DECREASE SUFFICIENTLY THIS AFTERNOON COUPLED WITH TRAILING ASCENT FROM SHORTWAVE TROUGH MOVING ACROSS TN AND MAY RESULT IN A FEW STRONG TO SEVERE STORMS GIVEN THE EXPECTED LARGE CAPE/MARGINAL SHEAR ENVIRONMENT. ..HALES/STOPPKOTTE.. 04/08/2011 CLICK TO GET WUUS01 PTSDY1 PRODUCT Link to comment Share on other sites More sharing options...

SHOWERS AND THUNDERSTORMS WILL BE OUT OF THE AREA BY EARLY SUNDAY MORNING. :gun_bandana: LITTLE COOL AIR FOLLOWS THIS FRONTAL SYSTEM AS STRONG RIDGE BUILDS IN ACROSS THE SOUTH CAROLINA AND GEORGIA AREA SUNDAY AND MONDAY. THIS WILL CAP THE ATMOSPHERE ALLOWING TEMPERATURES TO RISE TO NEAR 90 DEGREES ON SUNDAY.. THE RECORD HIGH FOR SUNDAY AT COLUMBIA METROPOLITAN AIRPORT IS 91 DEGREES AND THE RECORD HIGH FOR SUNDAY AT AUGUSTA BUSH FIELD IS 90 DEGREES. THE RIDGE WILL MOVE OFF THE ATLANTIC COAST MONDAY AS A STORM SYSTEM AND ASSOCIATED COLD FRONT DEVELOPS OVER THE MIDWEST. THE APPROACHING FRONT WILL GIVE THE AREA A CHANCE OF SHOWERS AND THUNDERSTORMS MONDAY EVENING THROUGH EARLY TUESDAY MORNING. UNCERTAINTY IS TOO GREAT TO INDICATE WHETHER OR NOT THESE STORMS HAVE THE CHANCE TO BECOME SEVERE. MODEL GUIDANCE DIVERGES SOME WITH MOVEMENT OF THE FRONT...THE NAM IS WEAKER AND SLOWER IN MOVING THE FRONT THAN THE GFS...LEANED TOWARD FASTER GFS.

blueheronNC Posted April 8, 2011 Share Posted April 8, 2011 Appears that a convergence boundary is slipping ESE across central NC right now. Seems like subsidence is filling/clearing out instability behind this boundary off the Blue Ridge. Think any convective initiation will be to the S of the Triangle over upstate SC, the Sandhills and coastal plain, perhaps associated with some mid-level energy that seems to be entering upstate SC at the moment: Link to comment Share on other sites More sharing options...
