1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 22.3N 90.6E,
APPROXIMATELY 69 NM WEST OF CHITTAGONG, BANGLADESH. ANIMATED
INFRARED SATELLITE IMAGERY DEPICTS A BROAD AREA OF LOW PRESSURE
ALONG THE BANGLADESH COASTLINE, WITH CONVECTIVE BANDING OVER
THE BAY WRAPPING INTO THE CENTER. THE CONVECTIVE ORGANIZATION
HAS IMPROVED SIGNIFICANTLY OVER THE PAST 12 HOURS AND THE 850 MB
VORTICITY SIGNATURE IS BECOMING MORE SYMMETRIC. A 261533Z ASCAT
PARTIAL PASS REVEALED 30 KNOT WINDS UNDERNEATH THE DEEP CONVECTION.
THIS CONVECTION IS BEING ENHANCED BY STRONG UPPER LEVEL DIFFLUENCE;
HOWEVER, FUTHER ORGANIZATION IS HAMPERED BY MODERATE TO STRONG
VERTICAL WINDSHEAR (20-30 KNOTS) IN ADDITION TO FRICTIONAL EFFECTS
WHILE THE LOW LEVEL CIRCULATION CENTER REMAINS OVER LAND. NUMERICAL
GUIDANCE SOLUTIONS DEPICT THIS DISTURBANCE TRACKING VERY SLOWLY
WESTWARD ALONG THE COASTLINE INTO INDIA OVER THE NEXT THREE DAYS.
IF THE DISTURBANCE WERE TO TRACK JUST SLIGHTLY FURTHER SOUTH,
THE WARM WATERS OF THE BAY AND GOOD OUTFLOW MAY ALLOW FOR RAPID
DEVELOPMENT OF A TROPICAL CYCLONE. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF
A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS MEDIUM.
(2) NO OTHER SUSPECT AREAS.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED AREA IN PARA 1.B.(1) AS A MEDIUM//

SYNOPSIS

Most of the Central, SW, S and SE Europe is covered with highly unstable warm and moist tropical air mass with dew points up to 20C. A ridge extending from Azores up to Iberian Peninsula inhibits convection in this region. Strong capping inversions are also present in the Apennine and most of the Balkan Peninsula. Weakening high is places over Black Sea while the numerous troughs are located over British Isles, Scandinavia and N Russia. Jet streak separating polar and tropical air mass is stretching from the N Atlantic trough England, N Germany and Poland up to Russia. Within this jet, a short-wave with thermal low is predicted to provide a good overlap of instability, moisture, lift and wind shear over parts of Germany, Poland and Belarus.

DISCUSSION

…Germany, Poland, Belarus, NW Ukraine…

Particularly severe weather is expected in the afternoon hours within the shortwave that will pass these countries in the forecast period and provide the great source of lifting mechanism. An overlap of SB CAPE exceeding 1000-2000 J/kg and DLS over 20-25 m/s in the large area extending from central Germany up to Poland is expected to produce widespread severe weather. Around noon, convection should start over Germany and most likely in the form of the supercell thunderstorms produce damaging wind gusts and large to very large hail. An increased 0-1km SRH over 100 m2/s2 and LLS exceeding 10 m/s cannot rule out tornado occurrence within these cells. In the afternoon hours CI should also take place in W Poland. Since these cells will form in the highly unstable (1500-2000 J/kg) and strongly sheared environment (DLS ~ 25 m/s, MLS ~ 20 m/s, LLS ~ 15 m/s, 0-3km SRH up to 300 m2/s2) with the support of the QG lift, an organized squall line is likely to form. It is likely that such a squall line will contain bow echos and the wind gusts within these may exceed 33 m/s. The transformation into derecho cannot be ruled out. Level 3 denote the area where according to the current understanding and NWP data the movement of this line is the most probable. However, models are not consistent with the direction of the MCS movement, some of them predicts propagation of the squall line to the Belarus, while some of them shifts the system more to the warm air mass. It is possible that an early-hours convection that will pass through N Poland may provide conditions more conducive for MCS turning more to the S. Due to these uncertainties, both scenarios are partially included in the level 3 area. Although the main threat are damaging wind gusts, conditions in the late afternoon hours (when the relative humidity will drop and thus the LCL) will be conducive for tornadoes, especially in the E Poland. An impressive overlap of 0-1km SRH ~ 400 m2/s2 with LLS ~ 12.5 m/s and CAPE ~ 1000 J/kg may result in a significant tornado event if isolated or embedded supercells will be present. These may be possible in the southern flank of the squall line. Within these storms very large hail is also possible. It is predicted that the MCS will enter Belarus and parts of Ukraine in the late evening hours and weaken, but still will be capable of producing severe wind gusts. If derecho will form, the system may be capable of producing damaging wind gusts also in the late evening hours, therefore level 3 is also extended to the parts of Belarus further east. Extreme values of PW (40-45 mm) may also result in a large precipitation amounts on the track of the MCS.

…parts of UK, Denmark, Netherlands, N Germany, Baltic Sea…

Although models predicts very large DLS over these areas (25-30 m/s) they are not as consistent with thermodynamic instability. Thunderstorms that will form within the short-wave may become supercells and create threat for the large hail and severe wind gusts. However, due to limited thermodynamic instability, limited boundary layers moisture content and rather low-topped convection, such a threat deserves only level 1.

…Germany, Switzerland, N Italy, Austria, Czech Republic, Slovakia, W Hungary, Belarus and NW Ukraine…

Locally enhanced DLS up to 15 m/s with CAPE up to 2000-2500 J/kg and rich boundary layer’s moisture (mixing ratio up to 12-13 g/kg) create threat for multicell and supercell thunderstorms where severe wind gusts and large hail are likely. DMC is forecast to start around noon and the storms should weaken in the late evening hours. In the areas where the storm motion is predicted to be very low (DLS below 10 m/s) excessive precipitation and local flash flooding cannot be ruled out, especially in the NW parts of the Italy.

…S Finland, parts of Russia…

Favorable overlap of DLS around 20 m/s and CAPE up to 400-600 J/kg create threat for supercell thunderstorms and thus severe wind gusts and large hail. Uncertainty related to CI, low thermodynamic instability, limited boundary layer’s moisture content and narrow zone where the CAPE overlaps with the favorable shear makes the threat marginal. The highest threat for the occurrence of severe weather falls on the early afternoon hours.

…NE Spain…

Low-level inflow of impressive rich boundary layer’s moisture content (mixing ratios up to 16-18 g/kg) overlapping with steep lapse rates (~ 7 C/km) locally will enhance CAPE values to 2000-2500 J/kg. If thunderstorms will be able to get through the cap, they may be capable of producing large hail. Since the storm motion in this area is predicted to be very low, given the high moisture content excessive precipitation cannot be ruled out.

Valid: Sun 19 Jul 2015 11:00 to Sun 19 Jul 2015 14:00 UTC
Issued: Sun 19 Jul 2015 11:51
Forecaster: GROENEMEIJER

At 11 UTC a warm front was located along a line from near Leipzig to Poznan to Warsaw. An MCS / area of convective rain over NE Germany has created an outflow boundary that stretches from Berlin to Leipzig.

Along the warm front distinct surface convergence is taking place and low-level humidity is rather high with 18-21 C observed dew points. With 26-30 C surface temperatures, around 1000 – 1500 J/kg of MLCAPE should already be in place.

The Bayreuth, Lindenberg and Doksany profilers and Poznan radar confirm that 20-25 m/s WSW winds are in place at 3-4 km AGL, implying that strong to very strong wind shear is present.

Storms, probably elevated have formed in the Leipzig area and further south across the Czech Republic. It is expected that these storms will move eastward and become surface based. It is possible that storms will rather rapidly develop into a squall-line and that the wind risk will increase rather quickly.

In addition, more storms may form further to the east along the warm front after 13 UTC. Any isolated storms that manage to form will quickly turn into powerful supercells with a risk of large hail and severe wind gusts.

The high (about 300 m2/s2) SREH and anticipated strengthening low-level shear that is in place along and slightly to the north of the warm front suggests that tornadoes cannot be ruled out. However, in most places, the LCL height is rather high for tornadoes with T/Td spreads around 10 C, limiting this risk. An exception is a small area along the warm front where prior rainfall occurrs before the arrival of storms, cooling and moistening the boundary layer.
