Eskimo Joe Posted June 26, 2023 Share Posted June 26, 2023 If you have radar scope, you can get longer range base reflectivity from the terminal radars. Should be 'Long Range Reflectivity', second option from the top when selecting what mode you're viewing. 2 6 Link to comment Share on other sites More sharing options...

Kmlwx Posted June 26, 2023 Author Share Posted June 26, 2023 Any rotation at range should be taken with a grain of salt - you're seeing a higher level of the storm than you would be if the radar was closer. Link to comment Share on other sites More sharing options...

Eskimo Joe Posted June 26, 2023 Share Posted June 26, 2023 Updated LWX AFD Quote AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC 254 PM EDT MON JUN 26 2023 .SYNOPSIS... AN UPPER LOW CENTERED OVER THE GREAT LAKES WILL SLOWLY PROGRESS EASTWARD THROUGH TUESDAY, EVENTUALLY DRIVING A COLD FRONT THROUGH THE AREA TUESDAY AFTERNOON. THEREAFTER, HIGH PRESSURE WILL BUILD IN FROM THE WEST. AN AREA OF LOW PRESSURE WILL TRACK INTO THE GREAT LAKES THIS WEEKEND. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... A SURFACE TROUGH HAS ALLOWED CONVECTIVE INITIATION TO START OFF ACROSS THE ALLEGHENY FRONT AND POINTS FURTHER SOUTH. THESE SHOWERS AND THUNDERSTORMS ARE EXPECTED TO TRACK FURTHER EAST THROUGHOUT THE AFTERNOON AND EVENING HOURS. EARLY MODEL RUNS THIS MORNING AND EARLY AFTERNOON HAVE SUGGESTED THAT SEVERE POTENTIAL HAD DIMINISHED SLIGHTLY COMPARED TO 24 HOURS AGO. SOME GUIDANCE MAY HAVE BEEN UNDERMINING THE DEWPOINTS FOR THE EARLY AFTERNOON, AS LATEST OBSERVATIONS HAVE 60S/70S ACROSS MUCH OF THE AREA. AS THIS SURFACE TROUGH CONTINUES FURTHER EAST, IT WILL APPROACH MORE FAVORABLE LOCATIONS IN TERMS OF INSTABILITY AND SHEAR COMPARED TO FURTHER WEST. EARLY CLEARING ACROSS THE WESTERN HALF OF THE AREA HAS CONTINUED WITH A STABLE CLOUD LAYER DRAPED ACROSS PORTIONS OF NOVA AND NE MD DIMINISHING NOW. 18Z KIAD RAOB SUGGESTS FAVORABLE LAPSE RATES FOR STRONG TO SEVERE HAIL EARLY THIS AFTERNOON. ORIGINAL THINKING OF A MORE STABLE LAYER MAY BE OVERCOME BY THE INCREASED INSTABILITY JUST ABOVE WITH GOOD MIXING DOWN TOWARDS THE SURFACE. GUSTY WINDS AND LARGE HAIL REMAIN THE PRIMARY HAZARDS BUT CANNOT RULE OUT AN ISOLATED TORNADO AND ISOLATED INSTANCES OF FLOODING FROM TRAINING STORMS IF POSSIBLE. A SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR THE MAJORITY OF THE AREA THROUGH 9 PM. THE THREAT LIKELY DIMINISHES FROM WEST TO EAST THROUGH THE EVENING AND EARLY OVERNIGHT HOURS. DRYING CONDITIONS WILL BUILD IN LATE TONIGHT WITH PATCHY FOG POSSIBLE OVERNIGHT WITH LOWS IN THE 50S TO 60S. 3 Link to comment Share on other sites More sharing options...

batmanbrad Posted June 26, 2023 Share Posted June 26, 2023 satellite loop definitely showing the fairly rapid clearing taking place ahead of the lines of storms out to the west towards Harrisonburg. Still holding out some hope for some action here in Gaithersburg if enough insolation can occur to destabilize us more. Link to comment Share on other sites More sharing options...

southmdwatcher Posted June 26, 2023 Share Posted June 26, 2023 Well, it would've been nicer to have 7.3 midlevel lapse rates and 8 plus on the lower levels. Link to comment Share on other sites More sharing options...
