Hurricane Alex slams ashore in northern Mexico with 105mph winds
STRONGEST JUNE HURRICANE SINCE ALMA OF 1966
By Mark Vogan
As expected by some, Hurricane Alex rapidly lowered it's pressure to 947mb and those winds did eventually respond to the lowering of pressure within the center. Alex's roared ashore around 10pm ET within a sparsely populated area of Soto La Marina which is on the northeast Mexican coast, roughly 35 miles north of La Pesca, Mexico and 110 miles south of Brownville, Texas. Maximum sustained winds were thought to have been around 105mph at landfall. Hurricane-force winds did indeed remain "south" of the Rio Grande, however tropical storm-force winds extended 205 miles out from the center and therefore a persistent pounding of storm-force winds and torrential rains impacted Brownville, Harlingen and all the way up to near Corpus Cristi.
WHY DID ALEX INTENSIFY UP TO LANDFALL?
1) WELL ORGANISED CIRCULATION
2) VERY WARM WESTERN GULF WATERS
3) VERY LOW WIND SHEAR ALOFT AND A GOOD UPPER RIDGE OVER TOP OF THE STORM.
NEW ORLEANS AND THE OIL SPILL
For the past 24 or so hours now, heavy showers and strong thunderstorms have pushed onshore along the central Gulf Coast with Alex associated weather reaching as far nortth and east as the Florida panhandle. The gusty winds blowing north is unfortunately pushing the oil onshore from western Louisiana likely to the Alabama or even Florida coast, this of course isn't good news.
Increased moisture has kept the New Orleans area mostly cloudy with periods of heavy thunderstorms, gusty windy conditions and a reduction in temperature due to increase cloudiness and rainfall which likely have dumped 2-4 inch rains from southeast Texas all the way to Alabama and the Florida panhandle, despite Alex being over 500 miles away from New Orleans.

Hurricane Alex drenches Mexico's northern coast
Associated Press/Weather Channel
SAN FERNANDO, Mexico (AP) -- Hurricane Alex ripped off roofs, flooded streets and forced thousands of people to flee coastal fishing villages as it pushed into northern Mexico.
The Atlantic season's first hurricane largely spared nearby Texas, which had prepared for a possible direct hit. While it spawned two tornadoes and caused 1,000 people to evacuated low-lying areas there, state officials reported no injuries or major damages.
Earlier, Alex whipped up high waves that frustrated oil-spill cleanup efforts on the other side of the Gulf of Mexico and delivered tar balls and globs of crude onto already soiled beaches.

northeast
A simply gorgeous first day of July and what more could you ask for? Abundant sunshine, low humidity and highs of 80 for Washington DC, 79 in Baltimore, 78 in Philadelphia, 77 in New York and 73 in Boston. With a dry, Canadian high in place with a very comfortable day, the nightime temps will be even more comfortable with 65 degrees for DC and Baltimore, 65 for Philadelphia and 64 for New York with 50s in Boston.... We may even see a few 40s and even 30s across interior New England since the air is pretty dry.
southeast
The influence of the large trough now over the eastern half of the nation is allowing lots if sunshine and comfortable highs throughout the Southeast. Only the Gulf coast and as usual Florida will see thunderstorm development. Highs today will bearound 86 for Atlanta with sunshine, lows around 72 whilst New Orleans has an increased storm risk as usual for the time of year with a high around 83 degrees which is below normal and quite nice compared to recent times. Lows in N.O. shuld hover around 74 degrees tonight with storms lingering. Florida will see storm chances throughout the state with highs ranging from 86 and lows of 75 at Jacksonville to highs of 90 at Orando and lows of 74 to Miami with highs around 91, lows around 78-80.
southwest & northwest
Sunny and hot is the name of the game... Highs are expected to top 107 for Las Vegas and 111 for Phoneix with lows in the low to mid-80s.... 70s along the coast, 80s and 90s for inland valleys...
southern plains
A relatively cool day from south Texas with daytime 80s and temps as low as upper 70s for northwest Texas. Highs around 90 for Dallas.

AFTER MID TO UPPER 90s OF LATE AND NOW A REFRESHING AIR MASS IS CURRENTLY IN PLACE, HOW HOT WILL THE EXPECTED HEAT WAVE OF NEXT WEEK BE FROM WASHINGTON TO BOSTON?
TURN OFF THE AC AND OPEN THOSE WINDOWS
After I-95 morning lows in the low to mid-60s with even some 50s in rural areas away from the urban heat island, it was a stunning day with plenty of sun and highs generally in the mid-70 to 81 degree range. You really couldn't ask for better folks in this area at this time of the year. A cool, Canadian high pressure cell dominates, keeping the refreshing and much drier air flow down from Ontario.Those pleasantly warm days with low 70s along the shore cool quickly at night due to the "dry air" and we see lows fall away during the overnight.
GET READY TO TURN ON THE AC, AGAIN!
Unfortunately today will be one that's history soon enough as the warmer, sub-tropical flow begins to crank up over the weekend and the warmth will build BIG TIME... July 4th weekend promises to be a scorcher and we may be looking at dew points again in the mid-70s at times and highs that hit the mid-90s from DC to New York on Sat-Sun and perhaps a run at 100 for Mon-Tues... Realfeels in the 105-110 range is very likely indeed with highs expected to top between 98-102 degrees Monday through Wednesday next week. Lows are likely to fail to drop below 80 degrees in the cities at night so make sure that AC is in good working order...

TODAY'S COND
A fairly cool but humid day with overcast skies and with periods of heavy showers throughout the day, clearing by mid-afternoon and allowing some sunny spells as well as some warming. The unsettled weather continues of a trough is sitting just to the northwest, however with high pressure and heat persisting over central and southern England, central Scotland is right under the boundary between cool and warm air masses..
Thanks for reading.
