    Finally B) After 7 days of the "Beer"...........I mean Death Ridge we have a great pattern coming up. Have picked up Andy from DFW Airport and amazingly got to Dodge City (Kansas) to be centred between the 2 big areas for tomorrow, will make a decision in the morning for Wyoming or the Panhandles of Texas, but at last it looks like a Severe end to May and With Thursday looking like the Big day this should be the warm up event.

    DAY 1 CONVECTIVE OUTLOOK

    NWS STORM PREDICTION CENTER NORMAN OK

    1258 AM CDT WED MAY 21 2008

    VALID 211200Z - 221200Z

    ...THERE IS A SLGT RISK OF SVR TSTMS OVER PORTIONS OF THE CNTRL HIGH

    PLAINS...

    ...SYNOPSIS...

    LARGE-SCALE OMEGA BLOCK WILL PERSIST ACROSS NORTH AMERICA THROUGH

    THE DAY ONE PERIOD WITH THE PRIMARY FEATURE OF INTEREST BEING

    EVOLVING UPPER LOW OVER THE INTERMOUNTAIN WEST. IN THE LOW

    LEVELS...PRIMARY LEE CYCLONE IS FORECAST TO DEVELOP SEWD FROM CNTRL

    OR ERN WY INTO ERN CO. AS THIS OCCURS...BAROCLINIC ZONE CURRENTLY

    QUASI-STATIONARY ACROSS CNTRL TX WILL LIFT NWD AS A WARM

    FRONT...LIKELY EXTENDING FROM SURFACE LOW SEWD THROUGH THE ERN TX

    PNHDL INTO SRN OK BY EARLY EVENING. THIS BOUNDARY WILL THEN

    CONTINUE SEWD THROUGH CNTRL LA AND THEN EWD ALONG THE GULF COAST TO

    NEAR THE GA/FL BORDER. FINALLY...A DRYLINE WILL BECOME INCREASINGLY

    WELL DEFINED OVER WRN TX TODAY WITH THIS BOUNDARY INTERSECTING THE

    WARM FRONT OVER NWRN TX OR THE SERN TX PNHDL LATER THIS AFTERNOON.

    ...CNTRL PLAINS...

    STRENGTHENING LOW-LEVEL FLOW E OF SURFACE LOW WILL AID IN THE NWWD

    RETURN OF AN INCREASINGLY MOIST BOUNDARY LAYER WITH DEWPOINTS

    INCREASING INTO THE 50S OVER KS...AND MID/UPPER 40S INTO CNTRL/ERN

    WY. THIS MOISTURE RETURN WILL OCCUR BENEATH A PLUME OF STEEP

    MIDLEVEL LAPSE RATES RESIDING ON ERN PERIPHERY OF EVOLVING UPPER

    LOW...CONTRIBUTING TO AFTERNOON MLCAPES OF 500-1000 J/KG INVOF WARM

    FRONT/LEE TROUGH.

    SUSTAINED CONVERGENCE NEAR SURFACE LOW AND INCREASING UPSLOPE FLOW

    TO THE N OF IT WILL PROMOTE SCATTERED TSTM DEVELOPMENT BY MID/LATE

    AFTERNOON OVER CNTRL/ERN WY WITH STORMS PROGRESSIVELY BUILDING SWD

    INTO NERN CO. DESPITE LARGELY MERIDIONAL MID AND HIGH-LEVEL WIND

    FIELDS...BACKED LOW-LEVEL WINDS TO THE N OF SURFACE LOW WILL RESULT

    IN SUFFICIENT DEEP-LAYER SHEAR FOR ORGANIZED/ROTATING STORMS WITH

    THE PRIMARY SEVERE WEATHER THREATS BEING LARGE HAIL AND LOCALLY

    DAMAGING WINDS.

    A NW-SE ORIENTED BAND OF ELEVATED TSTMS IS EXPECTED TO DEVELOP LATER

    TONIGHT FROM WRN PARTS OF SD/NEB SEWD TOWARD THE LOWER MO VALLEY AS

    WAA/ISENTROPIC UPGLIDE ARE ENHANCED TO THE N OF RETREATING WARM

    FRONT AND ALONG STRENGTHENING/EXPANDING LLJ AXIS. SOME OF THE MORE

    INTENSE STORMS WILL BE CAPABLE OF MARGINALLY SEVERE HAIL.

    ...SRN PLAINS...

    AIR MASS E OF DRYLINE AND ALONG RETREATING WARM FRONT IS EXPECTED TO

    BECOME MODERATELY UNSTABLE THIS AFTERNOON WITH MLCAPES INCREASING TO

    1000-2000 J/KG. WHILE DEEP LAYER SHEAR WILL NOT BE PARTICULARLY

    STRONG /0-6 KM SHEAR AOB 30-35 KT/...LOW-LEVEL HODOGRAPHS ARE

    FORECAST TO REMAIN FAIRLY LARGE...NAMELY ALONG WARM FRONT. ANY

    SEVERE WEATHER THREAT WILL BE CONDITIONAL ON WHETHER A STORM CAN

    DEVELOP AND BECOME SUSTAINED. GIVEN THE HIGH UNCERTAINTY...ONLY LOW

    SEVERE WEATHER PROBABILITIES WILL BE INCLUDED ATTM.

    Todays risk as thought has been extended further South to just West of our position here at Dodge City, so most of the hard work with regards to driving has now been done.

    Also the next seven days look Unreal, have we a lucky mascot in our ranks with Andy ;):);)

    Hi Paul

    Between a rock and a hard place at the moment. Have the models changed significantly over night? Dave was still looking at his original target area. Somewhere around Chyenne. That is about a two hours drive north west of our location. Will keep you posted when I get an update.

    Probably the best risk for severe storms today would be just south of a line from Limon CO east to about Scott City KS.

    I would not rule out other activity further north in WY but the set-up includes a fairly moist air mass for the region heading north out of NM, so the environment will become highly unstable with the developing hot air mass not able to make much penetration north of the line I specified due to the anchoring effect of the old front which has reached east TX and slants back to northwest into Colorado towards developing strong low pressure.

    Tomorrow the action should involve more of a dry line with more Gulf moisture also streaming north into KS and OK, the action should shift only slightly towards Hill City KS.

    Looks like a fantastic setup Paul. I'll be watching closely.

    Julie, doesn't matter that your post isn't weather realted. The forum needs to know what that young fella is up to.

    Having spent 13 days with the lad I can assure you that he is a model of a human being. He never swears, resects all animal and plant life, doesn't drink (in the states anyway) and is a mean GPS operator.

    He also hates AbbA with a passion.

    I would be very surprised if that man has any regrets for anything he's done in his life. Ever!

    ;)

    We are sat on a dirt track just west of Burlington and have a Developing Supercell literally 15 miles in front of us, explosive Updraughts and this is going to move just North of us, the 1st cell of the day ;)

    If you recall that event over Jetmore KS over a week ago, something similar is indicated here from J-field analysis, STRONG peak of energy at 23z to 01z should create a fast-moving bow echo type event moving ESE then SE into Kansas, likely to track across Scott City then just north of Garden City towards Dodge City.

    "A FEW LONGER-LIVED STRONG TORNADOES"

    Sounds pretty cool having that on a weather forecast ;)

    Quite a few chasers live streaming near Wray CO at the minute, no tornado yet I don't think, but it must be promising.

    we have had fun today chasing a few cells they were never going to produce tornados so was able to core punch without worrying to much currently in north east CO getting ready to punch a few more cores

    Glad to hear you're there, that one looks quite strong on the radar here ... and that J-field energy peak I mentioned is at 0130z (about 37 min from now) ... after that, I think these storms may rapidly fan out into w KS even though cell motion has been northeast, the activity zone will shift east overnight.

    we stopped to watch the cell on 24 just by seibert and the storm forms a meso just above our heads we thought we were going to be tornado damage thankfuly it passes over we start to head east to get a good vantige point and just before we got to Vona we spotted a tornado on the ground out of the back of the car me and Paul saw it I frantickly tried to get a shot off with my camara but the light was not good enough for the shot we will check but were not sure we then sat and watched it try and produce another we then dashed east trying to outrun the updraft and Paul has bagged some amazing lightning bolts we hope to post up te pictures soon we will continue to watch the lightning show for a while then head further east or the night what an amazing days chasing i'm sure the guys will post once we get a base camp for the night

    Phew

    Knackered and what a Chase day it turned out to be, started slowly but we got to within 20 miles of Dryline Initiation, followed LP Supercells, all looked crap until 6pm when we went after the Kit Carson Cell, I will leave it up to Andy to describe today in the next post but suffice to say he is absolutely in awe of what we saw today, always Chase a Slight risk because you never know what will happen, today proves that.
