Weather Talk

BRUTAL HEAT GRIPPING THE AMERICAN SOUTHWEST

Whilst the coastal plain of the Northeast is underneath a canopy of warm muggy air with Philly currently 83 degrees and Boston 74 degrees, the interior of New England is cool with only 50s. The seperation is two different air masses is courtesy of a front! Severe thunderstorms have and are still rolling through the Boston area (see New England Weather Watchers on Facebook for GREAT video of the storms rolling through Boston) and is producing amazing lightening, gusty winds and drenching rains.

The Midwest saw brutalizing severe tornadic thunderstorms which brought death and devastation to Illinois and Michigan. The collision of heat pushing up from Texas and the cooler, drier air seperated and mixed over the Midwest by a powerful; Pacific storm system was the creator of such weather... See stories above for more.

The Southwest Deserts have seen a cool, unsettled spring, well the heat has rapidly caught up with the season as highs are currently pushing 110 across many lowyling desert locales with Las Vegas sitting at 108 and Phoenix 107. Laughlin, Nev is at 109 and Death Valley, Calif is at an impressive 118 degrees. As I stated in my video earlier today on Facebook I expected a high in Death Valley to top at or near 120 degrees in the coming days and it likely will reach or surpass that reading today! Even El Paso is at 107 degrees right now.

At present the tropics are quiet with the exceptions of "Phet" in the Arabian Sea/Gulf of Oman and has now hit Pakistan.

Vagaries of the Weather
India & Sub-Continental Asia Weather

"Phet', now tired,has never-the-less spent out its fury in Pakistan today.With gusty winds,there was very heavy rainfall in Southern and Coastal Pakistan since last night. Some of the rainfall amounts from Pakistan in mms, Gawader 227mm, Jiwani 194mm, Pasni 139mm,Karachi Masroor 133mm,Faisal 92mm, Sadar 92mm North Karachi 86,Karachi Airport 77mm, Landhi 66mm,Gulistan-e-Johar 61mm, Turbat 43.3m, Padidan 24.0,Nawabshah 22.0. Resultantly,all the heat wave spots are cooled down.

The system, erstwhile "phet", is now moving eastwards into India, via the Gujarat/Rajasthan international border. Its movement will bring some rain (and cheer) to the over heated desert regions and then into Haryana and Delhi, by Monday/Tuesday. By Wednesday,9th, as a weak low, it will crash into the Kumaon Himalayas in Uttaranchal. Hence, it can be presumed that finally, the system will die, but not before pouring rains in Uttaranchal on Wednesday.

Now, since this will move as a replica of a mini W.D, we must assume that no substantial increase in rainfall will be seen on the Karnataka /Maharashtra coasts till the 10th. of June. By 10th. June, Monsoon will just about totter to reach Konkan, as a feeble current.

By this I mean, the rainfall along the Karnataka and Konkan regions of the West Coast will continue to be meagre, and not really gain intensity till the 10th. The obvious assumption is also the fact that the interior regions of Maharashtra and Northern Karnataka will remain practically dry till the 11th of June.

The current MJO forecasts are still not very encouraging, and show the wet spell approaching the Northern Indian Ocean around the 15th. of June.But,at this stage I will not venture to comment on this, and have put in a word of caution mentioning this point in my previous blog.

The Bay has suddenly buzzed with activity today.Thick clouding is seen in the central bay, around the Andaman Islands, and the region must be watched for a "low" next week. On the synoptic situation, we can estimate some rainfall, moderate, along the Chennai coast till Tuesday, after which we see a 2 day dry spell. The same with the interior.After that,we must monitor the Bay for further estimates.

As if in defiance, an inland vortex is seen forming in the Goa region on Friday. Forecast models estimate varying amounts of rain in Goa due to this formation on Friday/Saturday. Forecasts vary from 50 mm/day to 150 mm/day.This small system is then seen moving into the Arabian Sea, and increasing rainfall over Konkan on the 12th.

Hottest in Asia: Al Ahsa Airport (Saudi Arabia), 48° and Basrah (Iraq), 48°
Hottest in India: Jharsuguda;45.5c.
Mumbai: High today at Colaba:36.0c,and at Santa Cruz:34.2c.Santa Cruz recorded 7.8mms of rain while Colaba had just 0.4mm.


Increase in rains expected temporarily for a day today, but the real increase in rain intensity will be from the 10th.
