September has been a warm month for the Eastern US but it looks like it’s turning cooler for October and the month is likely to begin very cold compared to normal in the Plains. In fact snow and record cold is possible as bitter cold air parked over Alberta and Saskatchewan drops south down the […]
It’s turned November-like over the western Prairies of Canada and this looks to be a hint of what’s to come further south as we depart Sept and say hello to Oct. Note the ridge building into AK. Here’s the GFS ensemble 6-10 2m temp anomaly for 6-10. CFSv2 2m anomaly for week 2 is more […]
Florence may not have lived up to it’s initial billing as the strongest Carolina hurricane in history but it certainly did for it’s excessive rainfall which has put large parts of North Carolina and South Carolina under water, killing 18 so far. Like with Harvey last year, Hurricane Florence stalled allowing rain bands to sit […]
Article from www.wunderground.com Bob Henson · September 14, 2018, 11:21 PM EDT Relentless rainbands sweeping around Tropical Storm Florence continue to drench parts of North and South Carolina already waterlogged after days of torrential downpours. Florence’s center—located about 40 miles west of Myrtle Beach, SC, at 11 am EDT Saturday, with top sustained winds down […]
Since my last post on Florence, the hurricane’s core has weakened in intensity and structure has become disorganized, likely due to dry air entrainment. However, despite it’s core winds (a small central portion of the storm) down from 140 to 110 mph, in a sense ‘the damage may have already been done’ because the system […]
We have an ocean to atmosphere feedback setup and pattern which could spell a serious problem to the US. Waters from the Gulf of Maine down to the Delmarva are running at record warm levels. SST’s of 84 degrees have been reported off Cape May, NJ. There’s an noticeable response in the atmosphere above with […]
Up until now the focus has been across the Pacific and it’s busy 2018 season while the Atlantic has remained quiet as expected. This is typical of warm ENSO years where the tropical east and west Pacific is warm and Atlantic cool. As you can see from the two below charts, there’s been a frenzy […]
Last August, Category 4 Harvey hit Texas with tremendous force. While wind and storm surge impacts were massive, the rainfall was simply off the charts as the vast system stalled for 5 days. 60.58 INCHES of rain fell on Nederland, TX setting a new record for most rainfall within a single US tropical cyclone. That […]
Summer 2018 will likely go down as warmest on record for parts of the West, wettest on record for parts of the East while cool in between. The cool Plains was a surprise but the hot West wasn’t. According to NOAA, June 2018 was the Lower 48’s 3rd warmest June on record. July was 11th […]
Western ridge + Ohio Valley trough + very warm water off NE = Record wet summer/year for East Coast!
With a mean Great Basin ridge and Great Lakes to Ohio Valley trough and lows sweeping over the Great Lakes into the Northeast/Mid-Atlantic, waves of Gulf and Caribbean moisture have frequently lifted north. With tropical air meeting incoming fronts from the west, major rainfall and flood events have been common place since June 1 from […]
