SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...

THE LATEST NAM WHICH WAS MUCH SLOWER IN ITS EARLIER RUNS FOR THE

PASSAGE OF THE UPPER TROUGH TOMORROW...HAS TAKEN THE LEAD AND NOW

BRINGING SEVERAL WAVES OF SFC AND LOW LEVEL BOUNDARIES ACROSS THE

AREA ON TUE - STARTING JUST AFTER DAWN. LOCAL HRRR RUNS SHOW THE

CURRENT NORTH-SOUTH LINE OF STORMS FROM CNTRL OH TO WRN NC

DISSIPATING OVER THE NEXT SEVERAL HRS...W/ ANOTHER SIMILAR LINE

MOVING IN FROM BEHIND.

WITH THE MAIN UPPER LEVEL LOW PRESSURE SYSTEM STILL A DAY AWAY

/CURRENTLY AFFECTING THE NRN PLAINS-WRN GREAT LAKES REGION/...

CONDITIONS WILL BE FAIRLY QUIET OTHER THAN SOME SCATTERED SHOWERS

AND A FEW BRIEF AND WEAK EMBEDDED CONVECTION. AS MENTIONED...THE

THICK CLOUD COVER OVERNIGHT AND INTO EARLY TUE WILL KEEP THE AREA

FAIRLY STABLE. A LIGHT SLY WIND AND WEAK MOISTURE SURGE WILL BRING

DEWPOINTS BACK UP INTO THE U60S AND L70S...WHICH WILL ENHANCE

WHATEVER MINIMAL INSTABILITY EXISTS. HOWEVER...LOOKING AT THE

SITUATION SYNOPTICALLY - THE MAIN LOW PRESSURE SYSTEM IS A CLOSED

LOW OVER THE GREAT LAKES THAT WILL MOVE A BROAD UPPER LEVEL TROUGH

ACROSS THE REGION.

DOWN ACROSS THE SRN APLCNS...THERE WILL BE ENOUGH OF A KINK IN THE

UPPER LEVEL FLOW TO ACT AS A BETTER LIFTING MECHANISM - WHILE THE

ENERGY OVER THE MID ATLC REGION WILL BE FAIRLY WEAK AND DISPERSED.

AS THE SFC COLD FRONT MOVES ACROSS THE CWA DURING THE AFTN/EVE HRS

/BEHIND THE INITIAL BANDS OF MORNING SHOWER ACTIVITY/...SOME

SCATTERED CONVECTIVE DEVELOPMENT WILL BE POSSIBLE EAST OF THE BLUE

RIDGE. BY THIS TIME...PARTIAL CLEARING AND MORE LOW LEVEL HEATING

DURING THESE BRIEF FEW HRS SHOULD ALLOW FOR ENOUGH INSTABILITY FOR

A FEW TSTMS /SOME STRONG-SEVERE/.

That's because there's absolutely no reason to have this thread... should have just kept it in the gen. obs. and/or gen. severe threads.

Y'all can have fun spending 2-3 pages complaining.

I'm going to laugh, and laugh hard, when we actually see something today.

And 2-3 pages of complaining is better than 15+ :whistle:

So will I :thumbsup: This damn summer convection!

Vis. Sat. is okay this morning... a bit clearer than I though it'd be. We'll have to watch the cloud deck out west and see if/when that pushes further east into our local area.

Typically you don't trust a model that has initialized so poorly. HRRR is showing a nice squall line rolling through the area right now and the radar is almost a clean sweep for hundreds of miles.

Did notice that, just nice to look at when your as desperate for rain as I am

Did it ever occur to that perhaps the model is right, and reality is wrong?
