Satellite imagery showing massive cloud with CB signs responsible for Thunderstorm. Thunderstorm also was reported in Pune... November month has never been so different. Rains have halted with partly cloud skies in Central India as moisture (most of the) has withdrawn.. With the bay low sweeping again, some more rains are expected to happen after 18th.

NOTICE-
METD WEATHER forecasts will not be available from Monday 22nd Nov 2010-Friday 26th Nov 2010 as I will be in Pune for some private work.. Forecast shall resume by Saturday,27th

Heavy Thunderstorm grips Vidarbha with rains. More expected

CAPE PLOT showing MAX CAPE over Central And Southern India


METD WEATHER

Severe Weather Forecaster

28mm rainfall was recorded at METD WEATHER hq due to a strong thunderstorm in afternoon hours of 11th Nov and evening-night-morning thunderstorm on 11th and 12th Nov.
Lightning with strong electric potentials were observed at night hours on thursday as strong backlights was observed followed by strong thunderstorm and moderate rains at late night continuing till early morning!

Rainfall also hit various areas of Vidarbha and North Central Maharashtra as the moisture deposited by the remnants of Cyclone Jal is colliding with the cool air from the north giving more cloud cover and rains at the center.

Moisture is going to continue well till 20th Nov which is due to remnants of JAL and then I see another low pressure in the bay doing so again.
So November in central India is expected to be warmer at nights and days.

Weather Forecast
Rains with mostly cloud cover will continue in Central India with rainfall chance with Thunderstorm in forecast as Strong CAPE coupled with daytime heating will trigger Cumulonimbus clouds formation and development.

Nagpur -
Rains are expected with thunderstorm again on Friday(12th Nov 2010) as daytime heating with CAPE will continue.

This November in Central India looks like June


METD WEATHER
Akshay Deoras
Severe Weather Forecaster

The GFS 850mb showing typical SW Monsoon signatures as blend of rich moisture has deposited over Central and Southern India due to the Tropical Cyclone JAL land sweep over much of Southern and Central India earlier this week. A typical feature which happens during Monsoon season in India as the bay low sweeps over Central India precipitating heavily in course due to moisture deposition.

Rainfall was widely observed in Eastern Maharashtra and Central Maharashtra on Monday with data recorder recorded light to moderate rains in Nagpur. Unfortunately no data was recorded at METD WEATHER hq as I was away (around 80kms) from the city on a short vacation.

The 200-300mb map is also showing the jet streams have a more southerly flow and extent, a typical monsoon feature. Such feature prevents formation and impacts of so called western disturbance or Extratropical storm originating in Mediterranean area and bringing rains and snow in North Inda. So as long as the GFS is showing good low level moisture at least till more than Half of November i.e ( upto 20th Nov) most of the areas will have warmer nights and early mornings than the sudden chilly dip which happened in late October.
Anticyclone is expected to build over North Central India in next week that might act like Monsoon withdrawal system and then permitting Winter.

COOLING CONTINUES IN NORTH INDIA
As North India is away from this low level moisture zone, cooling is continuing with minimum temperatures around 12-13C.
Srinagar is having min temperatures near to 3C.
The cool air is unable to move in Central India as the winds don't have a Northerly flow. They are southerly.

RAIN CHANCES IN CENTRAL INDIA
AS THE BLEND OF MOISTURE CONTINUES TO COLLIDE WITH THE ARRIVING COOL AIR FROM THE NORTH CONTINUES TO COLLIDE

He also told that there were floods in some areas and trees,powerlines down at some areas
Jal weakened significantly in the past few hours before the landfall and now as seen in the satellite imagery of 1PM, Cyclone JAL has totally disappeared.
