Today's Top Weather Stories
On Weather & Climate Through the Eyes of Mark Vogan
Current temps across many areas of the Southeast rose into the mid-90s but looking at current temps, some spots have dropped into the 70s, including New Orleans. Only powerful thunderstorms can drop temps like a stone....!

southeast
Todays marks a slight change from the past 4-6 days. The Bermuda high is being nudged SE and allowing a slight trimming in temps from Louisiana to west Georgia. Highs should be 1-3 degrees lower than yesterday and an increased risk of thunderstorms development as the air cools at the upper levels and allows a larger temperature contrast from surface to the upper levels... Mark's City-Cast as follows. New Orleans Hi 92 (dew point, mid to upper 70s), Lo near 80, 50& chance of an aft t-storm. Montgomery Hi 94, (dew point, 72-75 degrees), Lo near 72, 20-40% chance of aft t-storm. Atlanta Hi 93 (dew point near 72), Lo 72, 20-40% chance of aft t-storm. Jacksonville Hi 99 (dew point 75), Lo 80, 50% chance of aft t-storm.
Everywhere should feel-like at least 100 this afternoon with some spots feeling over 110.
southwest
The temperature slowly rises as the trough pushes east and allows the Four Corners ridge to pump. Most desert communities below 4,000ft should reach 100 by 3pm. Some places from Death Valley to Palm Springs down to the Salton basin, may run at levels between 105-115 degrees under brilliant sunny skies.
The big difference from recent days will be found across Salt Lake and Denber where today skies are sunny, dry and temps pushing into the mid-80s! What a change from the 60s and rain, eh?
Mark's City-Cast as follows. Los Angeles, Hi 80, Lo 65. (morning coastal cloud ans fog should burn to the coast by noon allowing skies to become clear and sunny. Palm Springs Hi, 105, Lo 75 (skies clear & sunny), Needles Hi 105, Lo 78 (skies: sunny) Las Vegas, Hi 100, Lo 78 (skies: Sunny) Phoenix, Hi 104, Lo 80 (skies: Sunny) Death Valley, Hi 115, Lo 83 (skies: Sunny), Denver, Hi 88, Lo 62 (sunny), Salt Lake City, Hi 85, Lo 68 (sunny)
northeast
The big rains and storms that have plaqued the midsection of the country of late is pushing towards the East Coast and today, the effects of the rain and storminess will impact the Mid-Atlantic with increased clouds and rain showers as well as the thunderstorm risk from Richmond to Baltimore, down into the DC metro this afternoon. Highs will be some 5-10 degrees lower than the past few days. 90s in DC yesterday will be LOW 80s today!. Meanwhile, the bad weather won't be impacting areas north of a line from Pittsburgh to Baltimore... It will be beautiful, sunny and warm with highs in the 70s for New England, 80s for the southern Northeast from Albany to Philly, including an 80 to 82 degrees for NYC, with clear, sunny skies and light winds this afetrnoon, what more could you ask for!
Mark's City-Cast as follows. Boston, Hi 77 (sun) New York, Hi 82, Lo 63 (sun) Philadelphia 85, Lo 70 (mostly sunny), Washington-Baltimore area, Hi 85, Lo 70 (storminess increases from west)
northwest
A new rain system pushes into the Pacific Northwest, bringing more showers for Seattle to Portland and points east of the Cascades. Highs range from the upper 50s in Seattle to low 60s in Portland. Only 70s to near 80 for areas east of the Cascades
southern plains
Texas will once again remain mostly sunny ans hot with highs ranging from the low to mid-90s from San Antonio to Beaumont whilst mid to upper 90s will impact a line from Lubbock to Dallas. Points further north will once again be under the gun of strong thunderstorms and heavy rains, though HOPEFULLY not as bad as what we've seen in Oklahoma. Highs should be in the mid-80s for OK City this afternoon.
northern plains
Unfortunately I have nothing new to tell you folks of the northern plaind and midwest. An area of low pressure and associated cold front will push west to east across the northern tier, helping instigate widespread showers and storms for many areas. High today may be slightly higher than of recent days with upper 70s reaching in North Dakota and low 80s in South Dakota, where sun is more prevalent. Minnesota and Wisconsin should see periods of rain and cloudiness with perhaps outbreaks of sunshine with highs running into the mid-70s. Areas further south and east from Chicago to the Mid-Mississippi valley, including St Louis, will see thunderstorms rather than plain rain showers as the air is warmer and more humid. Highs in the mid-Mississippi Valley should push into the 80s with upper 80s in St Louis to upper 70s for northern Illinois and Indiana. Mark's City-Cast as follows. Bismarck, Hi 79, Lo 59 (partly cloudy), Minneapolis, Hi 75, Lo 55 (chance of showers and storms), Chicago, Hi 77, Lo 58 (chance of showers and storms), St Louis, Hi 87, Lo 72 (sunny but chance of storms) GOOD NEWS IS, WE SEE DRYING OUT AND WARMER TEMPS TOMORROW AS SYSTEM PROGRESSES EASTWARD..

COMING UP SOON: DISCUSSION OF SCOTLAND AND UK WARMING TREND
Today will see a slight 1-3 degree trim back in temps from yesterday, particularly Louisiana, Mississippi and Alabama, even western Georgia. This is because the Powerful Bermuda high is shifting slightly SE which is also shifting the "strongest heights" away from where it's been hottest Louisiana and Alabama, lowering pressures will aid in producing perhaps highs in the low to mid-90s rather than mid to upper 90s with some 100s. For spots such as Atlanta and particularly southern and eastern Georgia, across to the Carolinas and into north-central Florida, the heat will still rise to levels of yesterday (95-100 degrees), perhaps with some spots topping yesterday's extreme levels. Remember 100s showed up across north Florida, south Georgia and the Carolinas yesterday and that was combined with humidity between 70-78 degrees.
COLD FRONTS OFTEN CRASH AND BURN OVER THE SOUTHEAST THIS TIME OF YEAR ONWARDS
Fronts tend to weak this time of year once they enter the northern Gulf states and often fade out before reaching the Gulf. The difference is typically enhanced thunderstorm potential and a trimming in temperature of a mere 10 degrees at best. Sometimes the air is drier as the front pushes the humid air down to around New Orleans, this can aid in cooling overnight lows from the typical upper 70s to low 80s along the Gulf coast to perhaps the low and mid-70s. From time to time, we may see a few days in which highs only warm to around 80 in Atlanta and lows fall into the 60s, but this is not often in a sub-tropical environment and it's when a cold front has been able to penetrate the dominant upper level that rules the South in summer, often forcing drier air.
88 degree low, 90 degree water
Ok, first of all, I checked out current surface coastal water temperatures were surrounding the Gulf and East Coast all the way to Jersey. It was interesting to see coastal waters now up as warm as 85 degrees at the mouth of Chesapeake Bay, I wonder whether this is accurate, just below this, it's 75 degrees, so perhaps.. I just thought 85 was pretty warm for only June but indeed strange currents and even a branch off of the Gulf Stream may play a role in making this correct at this locale. It also has been in the 90s in that region around DC and indeed 80s right on the beach there at Ocean City.
What I am not questioning is the water temps around the Gulf coast, check out those 80-88 degree temps showing now, those my friends are bathtube warm... Check out the 89 at Tampa Bay, or the 90 degree temp right off Key West...
Those 85-90 degree waters lead me to my next little topic.
The New Orleans to "real Gulf coast" region is always interesting. I say "real Guld coast" is because many including myself always thought New Orleans sat on the Gulf Coast. It's in fact some 50 miles to the south before you actually reach the coast itself. Amazingly the 75 dew points in New Orleans is often not too bad compared with a community named Boothevlle which is southeast of N.O. and is often in the low 80s for dew points and feels even worse, much worse than N.O. What facinated me was that when looking at the likely upper 80 degree waters that lap against the Mississippi Delta, southeast Louisiana coast, that is why we regularly see low 80 dew points, 92-94 degree heat and heat indexes through the roof.
The overnight low yesterday morning was a steamy, sticky, yuky 88 degrees. Remember that it was likely in the 90s most of the night down there with dew points probably as high as the mid-80s... same as those water temps.... Heat Index probably was over 100 through the overnight...
Currently 101 degrees at Jacksonville, FL

71-degree high here in Lennoxtown, Scotland signals what lies ahead!
Here in central Scotland, most places managed to top 70. Higher pressure from the sub-tropics has built back in and many places may enjoy several days which top the low to even mid-70s between now and Sunday. I believe high pressure from the sub-tropics will become the norm as we approach July which could be a HOT and very dry month....
TROPICS:
Still nothing new with the open wave that's in the central Atlantic. Shall update more tomorrow.
