Andrea Floods East Coast With 5-15″ Of Rain, California Eyes 125° Today!

Written by on June 8, 2013 in United States of America with 0 Comments

As forecasted, former Tropical Storm Andrea left her mark up and down the Eastern Seaboard Friday with record breaking rainfall from South Florida all the way the southern New England with 15″ falling in South Florida and a record 4-6″ across New York and Long Island. Even Boston saw over 3″ with water rescues having to be carried out.

I never thought Andrea would be much of a wind maker and despite producing 40-50 mph gusts along coastal Florida and along parts of the East Coast, it was the rain that caught the attention of millions as people became stranded in their cars as flood waters gathered around them in not just Florida but other parts of the Eastern coastal plain.

Despite Andrea heading north up the East Coast, the tail of the system whipped South Florida with one feeder band after another, dropping as much as 15 inches of rain on North Miami Beach and Golden Beach while Fort Lauderdale received 8.15″, drowning the old DAILY record of just 1.88″. 13 inches fell at Hallandale Beach. All this rain falling within such a short period of time (24 hours) brought major flash flooding throughout the Southeast urban corridor.

The Big Cities of the Northeast didn’t escape flooding either with New York City and Boston hit hard, experiencing water rescues as roadways went underwater thanks to 3-6 inches of rain, presenting a nightmare Friday evening commute.

Here are some of the noteworthy record rainfall totals from Andrea.

Ledyard Center, CT 6.30″

Madison, CT 6.20″

Old Bethpage, LI, NY 6.13″

New York (Central Park), NY 4.16″

Ashville, NC 3.42″

Water rescues had to be carried out up in the Boston, MA area where 3.07″ of rain fell.

While the remnant’s of Andrea speeds northeastwards across Atlantic Canada, it is said to energise the low out over the North Atlantic and will aid in bringing the UK it’s first appreciable rain in 8-10 days on Tuesday and Wednesday. See earlier post and video for details.

Record Heat Swelters The Southwest And Central Valley

The heat is building over the Desert Southwest up into the Central Valley with forecasted highs expected to top 110 widely this afternoon from Phoenix to Redding.

The ridge has been building over the past 72 hours with highs rising day by day and today appears to be the peak. Phoenix topped 110 yesterday while it hit 109 in Las Vegas. Today should see Sin City surpass today’s record of 111 with a high potentially levelling off at 112 or 113. The Central Valley is typically hot but today’s temperatures will be record breaking with levels only seen every so many years. In fact today’s temperatures are likely to be the Valley’s hottest since the blistering heatwave of 2006.

Yesterday saw Reno record it’s earliest 100 on record, breaking the old record by 6 days according to TWC’s Jon Erdman.

Here’s AccuWeather’s projected high’s today along with the records for the date.

This heat wave has been seen coming throughout the past week. It was also alluded to, that if you don’t like the heat and temperatures this hot, head to the beaches of Southern California as it will stay in the 70s, low 80s with a refreshing onshore breeze after morning mist and fog.

In fact there will be a significant temperature difference today and over the next couple between beach and desert. 70s vs 110-115, all thanks to a stalled upper low off the coast.

The ECMWF shows the upper low becoming more pronounced off the Southern California coast which means an enhancement of the marine layer along coastal areas with overnight fog and daytime sea breezes. This influence should penetrate a little further inland by early next week with Pacific air reaching into coastal valleys and canyons but beyond the bigger ranges and into the desert, it remains scorching hot.

The ECMWF a few days back showed the low moving inland, but not so much now as it has a stronger ridge, in fact it’s back to it’s original idea from early last week.

Here’s the ECMWF for Sunday

Though it doesn’t manage to get inland because the ridge is far too strong, the low will become stronger offshore, enhancing onshore swell and wind.

Note the 588dc thicknesses covering California and the 32C line at 850 over the Central Valley as well as deserts, that is why it should reach the 110s in Fresno in the San Joaquin Valley (southern end) and up in Red Bluff and Redding in the northern Sacramento Valley (northern end). Sacramento will be blistering too at around 109 to 110 but 3-4 degrees lower than the northern and southern end of the valley due to a slight westerly flow which blows air in from San Francisco Bay.

As heat builds over interior Calif, pressures lower and as pressure is higher offshore and air travels from high to low pressure. That is why winds will blow onshore and strong through the Sacramento River Delta. These winds of course loose their ‘cooling effect’ once they reach the Valley, becoming a ‘hot wind’ by enough to trim a couple of degrees off areas north and south where there is NO ocean effect.

As for Death Valley, well it topped a record tying 123 yesterday and should make it to 125 today.

Blistering Western Heat Spreads East Next Week!

El scorchio will spread east through next week with 100s reaching Texas, Oklahoma and Kansas thanks to the presence of passing lows to the north. Those passing lows will keep things cool, wet and active from Washington state to the Great Lakes. In other words the heat will be held to the south and forced east with the first 90 possible for Atlanta late in the week. Further north up into the Mid-Atlantic and Northeast, it’s likely to stay cool with highs in the 70s and 80s thanks to a weak trough.

Had the ground not been a wet across the Lower Midwest and Ohio Valley, the ridge may western ridge may have managed to builds NE across the country, remembering the feedback of the wet soils. Even in the soaked Southeast, the heat is likely to be tempered if it manages to get all the way to Georgia.

Here’s the ECMWF for next week.
