TODAY’S WEATHER ACROSS AMERICA By Mark Vogan

East Coast to endure ‘Scottish style weather’, Days of rain!

Radar shows tropical connection with cloud band stretching from Bahamas to just east of New Jersey, New York. 

With a stationary low divorced from the main jet stream, we’re talking DAYS OF RAIN THROUGHOUT MUCH OF THE EAST as the low is going to spin and spin and spin over a relatively small area. Like we saw last week with that large ocean system spinning off the Northeast coast which stopped a system over Ohio from progressing east, this is like that ocean system, only it’s over land.
Over Northern Virginia just now, the low has to it’s south and east a warm, moist flow spreading up from off the Southeast coast, feeding into the low. To it’s north and west is a cool, dry flow coming down, these elements will enhance rainfall throughout much of the Northeast over the next 24 to 72 hours at least! As this low strengthens. The concern is that later today, with a northward flow with origins in the tropics takes a turn more northeasterly into the system itself and inland over New Jersey, east, central Pennsylvania, New York and throughout the New England states, then we may be looking at perhaps 3-6 inch rains more widely from now till Wednesday rather than 1-3 inches with a bullseye of 7 or 8, rather than 6.

Renewed Severe Weather Threat for Southern Plains by Wednesday

As a new Pacific storm rolls into the West, wide spread rains and mountain snows prgress southeastwards, carving out a new western trough.

This will once again, build heights over the next 48 hours over the Plains, then a low redevelops to the lee of the Rockies, forms a cold front and this will swing west to east, slowly across the plains of Texas and Oklahoma, sound familiar?

The large-scale pattern remains exceptionally similar to last week over the country. The key difference will be that the ocean storm that was offshore last week is simply onshore this week, providing a very similar type of weather to what we’re seeing right now across Scotland. You folks moaning and groaning about gloomy skies, soaking, persistent rains should take heart, no. 1, at least you see temperatures in the upper 60s, 70s during even this dreary, persistent pattern, you can enjoy peaks of sunshine in between those hefty off and on showers and storms. We REGULARLY see days on end of literally no sun, heavy overcast skies, persistent rain and a chilly wind with an air temperature in the 50s!!

TODAY’S WEATHER ACROSS UK & EUROPE By Mark Vogan

UK looks unsettled for at least the next 10 DAYS! Upper low that brought stormy weekend to Alps becomes detached from jet stream swinging down into Med Sea bringing stormy, unsettled weather there

Mark Vogan discusses the Europe forecast in detail

The heart of Europe looks set to see a return to summer-like heat as the ridge expands northeastwards from Spain, thanks in part to the detachment of an upper low from the jet stream. This feature will swing into the central Med bringing likely gale force winds and stormy seas to much of the central basin, perhaps even bringing cooler, unsettled weather to areas as far east as Cyrpus and even the western fringes of the Middle East.

As for the UK, unfortunately a fairly strong upper low over Iceland will expand and deepen the trough back down into NW Europe and the UK. By Wednesday, we may see strong winds rattle in off the Atlantic with hefty showers piling in.

VAGARIES OF THE WEATHER
INDIA & SUB-CONTINENTAL ASIA WEATHER
BY RAJESH KAPADIA

Mumbai Update:

The way things were moving till yesterday, it was anticipitated that by Monday, the “high” pressure swirl in the Arabian Sea would strengthen, and the NW winds would, moving clockwise and coming from sindh/Gujarat, sweep over Mumbai.That was the Vararies forecast put up for Monday.

NW winds were to be hot, and projected to be at 37c today, while it is 31c (at 2.30 pm now).

Today, in the Arabian Sea,barring the N.Konkan area, the situation is much in tune. We see the winds getting weak after crossing Gujarat.(925 winds map above).

The reason is this (below). Seen in the map, the 700 hpa winds around Mumbai are the “culprits”. The mini vortex there has off set the 925 winds from blowing below the Gujarat coast in strength. And the vortex formed at 700 hpa caused the clouding.

Even the daily low cumulus over Mumbai are missing today.

There will be no meaningful rains in Mumbai… this spell should clear within 12 hrs..rain is expected next sunday, but it has nothing to do with this clouding..
