Valid: Thu 01 May 2014 06:00 to Fri 02 May 2014 06:00 UTC
Issued: Wed 30 Apr 2014 23:36
Forecaster: GATZEN

A level 1 was issued for the central Balkans mainly for excessive precipitation.

A level 1 was issued for the northern Aegean mainly for large hail.

SYNOPSIS

Weak geopotential is present across Europe, and the jet stream extends from the Bay of Biscay towards the Mediterranean Sea. Two vort-maxima will travel within the jet, one from Italy to Turkey, the other from the Bay of Biscay to the west Mediterranean Sea. Due to limited moisture over the Mediterranean, CAPE will be rather weak. Further north, moist and well-mixed air masses are still present from western into central and eastern Europe. Widespread convection will result during the period. Colder and dry air masses start to spread south from Scandinavia.

DISCUSSION

Greece, Aegean region

A short-wave trough moves east during the day, providing DCVA. The affected air mass is expected to become unstable in response to diurnal heating over Greece and onshore advection of modest moisture. Near the trough axis, initiation will be most likely, but weak vertical wind shear will limit storm organization. The best potential will therefore exist across the Aegean region, where an ageostrophic flow will evolve ahead of the vort-max. More than 20 m/s deep layer vertical wind shear are expected by latest GFS model run in the evening hours. Multicells and supercells may be capable of producing large hail. Given weak low-level vertical wind shear, tornadoes are rather unlikely.

   VALID 301200Z - 011200Z

   ...THERE IS A SLGT RISK OF SVR TSTMS FROM VA/MD/WV SWD TO THE FL
   GULF COAST...

   ...SUMMARY...
   SEVERE THUNDERSTORMS CAPABLE OF HAIL...DAMAGING WINDS...AND
   TORNADOES ARE EXPECTED WEDNESDAY ACROSS PORTIONS OF THE SOUTHEAST
   UNITED STATES...CAROLINAS...AND MID-ATLANTIC STATES.

   ...SYNOPSIS...
   A LARGE/PERSISTENT MID- AND UPPER-LEVEL LOW WILL MAKE SLOW EWD
   PROGRESS ACROSS THE UPPER MIDWEST THIS PERIOD...WHILE STRONG
   CYCLONIC FLOW SURROUNDING THE LOW BEGINS SPREADING ACROSS THE
   APPALACHIANS -- ESPECIALLY DURING THE SECOND HALF OF THE PERIOD. 
   ELSEWHERE...RIDGING WILL PERSIST BOTH UPSTREAM AND DOWNSTREAM OF THE
   LOW -- I.E. ACROSS THE W COAST STATES AND OVER THE WRN ATLANTIC/NEW
   ENGLAND -- THROUGH THE PERIOD.

   AT THE SURFACE...A COLD FRONT TRAILING FROM A NEARLY STATIONARY
   OCCLUDED LOW OVER THE WI VICINITY IS PROGGED TO ADVANCE ACROSS THE
   APPALACHIANS BY LATE AFTERNOON...AND THEN CONTINUE SLOWLY EWD ACROSS
   THE E COAST STATES OVERNIGHT.  WIDESPREAD THUNDERSTORMS AND
   ASSOCIATED SEVERE POTENTIAL CAN BE EXPECTED NEAR AND E OF THE
   MOUNTAINS.

   ...MID-ATLANTIC/EAST COAST STATES AND VICINITY...
   THUNDERSTORMS ARE FORECAST TO BE ONGOING ACROSS PORTIONS OF THE
   SLIGHT RISK AREA AT THE START OF THE PERIOD...INCLUDING THE FL
   PANHANDLE REGION/N FL AND INTO SRN GA WHERE AN MCS SHOULD BE
   ONGOING.  WITH ASSOCIATED CLOUDS AND PRECIPITATION LIKELY TO LIMIT
   AIRMASS DESTABILIZATION POTENTIAL IN MANY AREAS...EXPECT OVERALL
   SEVERE RISK TO BE SOMEWHAT HINDERED BY A
   SOMEWHAT-LESS-THAN-FAVORABLE THERMODYNAMIC ENVIRONMENT.  THAT
   SAID...WEAK HEIGHT FALLS SPREADING ACROSS THE AREA PROVIDING
   BACKGROUND UVV SHOULD HELP FOCUS AREAS OF LOW-LEVEL
   CONVERGENCE/ASCENT...FUELING A DIURNAL INCREASE IN STORM COVERAGE. 
   MEANWHILE...STRONGER FLOW ALOFT GRADUALLY SPREADING EWD ATOP
   LOW-LEVEL SLYS WILL RESULT SHEAR PROFILES SUPPORTIVE OF
   ORGANIZED/ROTATING STORMS.  THUS -- WHILE TEMPERED BY GENERALLY
   MODEST CAPE...EXPECT SEVERAL BANDS OF STORMS TO CROSS THE SLIGHT
   RISK AREA THROUGH THE DAY -- ALONG WITH ASSOCIATED RISK FOR DAMAGING
   WINDS AND SOME HAIL.  IN ADDITION...WITH VEERING/INCREASING FLOW
   THROUGH THE LOWEST FEW KM...SOME RISK FOR TORNADOES IS ALSO EVIDENT.
    RISK FOR SEVERE WEATHER -- THOUGH DECREASING SOME AFTER SUNSET --
   SHOULD CONTINUE THROUGH THE EVENING AND INTO THE OVERNIGHT HOURS AS
   THE COLD FRONT CROSSES THE MOUNTAINS AND SHIFTS EWD ACROSS THE RISK
   AREA.

Forecaster: PISTOTNIK

A level 1 was issued for a belt from the Netherlands towards the Balkans mainly for excessive precipitation and to a lesser extent for large hail.

A level 1 was issued for a belt from S Italy towards the Turkish West coast mainly for large hail and waterspouts.

A level 1 was issued for Central France for severe wind gusts and tornadoes.

SYNOPSIS

The main frontal zone is distinctly split into two branches, the Southern one running across the Mediterranean region and the Northern one across Scandinavia. In-between, rather low geopotential and weak gradients cover most of Europe. Two upper-level lows are moving from the Channel towards S France and from Central Italy to the Aegean Sea, creating an elongated stretch of unsettled and cool conditions. Warmer but equally moist air is present over Central Europe and over the Balkans, where a broad minimum of surface pressure has formed.
Weak anticyclonic influence creates dry and brighter conditions over Northeastern Europe. However, in the far North a cyclone moves from Finland into adjacent Russia, and a surge of polar air will enter most of Scandinavia in its wake.

   -- WILL ALSO DEVELOP ACROSS PARTS OF THE MID OHIO VALLEY AND NORTH
