April-June [s2If current_user_can(access_s2member_level1)] June-August Notice it has a strengthening El Nino with warmest waters shifting into the eastern Pacific while it remains very warm up the West Coast of North America and cold in the North Atlantic. This […]
Yesterday comprised as a day of record breaking contrasts. While 20-25 above throughout Southern California and as much as 40 ABOVE normal on the Northern Plains, it was 10 below normal with all-time snow records tumbling in New England. [s2If current_user_can(access_s2member_level1)] The models are all over the return of arctic air and further record setting cold as we […]
By Jon Erdman Published Mar 15 2015 10:18 PM EDT weather.com An over one-month snow siege has parts of New England threatening or already blowing past all-time records. Below, we have a rundown of heaviest snowstorm, snowiest month and season lists for the hardest hit parts of New England. Click on each bolded city link […]
While today we remain under the influence of the Scandinavian blocking high, feeding a modest chill in from a predominantly mild continent, we see this large system weaken and drift east through this week. An Azores high builds in to replace and this should herald some lighter winds and brighter skies also. Daytime temps will rise from […]
It’s been another hot summer-like day for Southern California and Southwest as well as the Northern Plains where records have melted. Temps widely 30-40 above normal throughout Nebraska and the Dakotas but it’s been quite different further east where winter’s returned to the Northeast with heavy snowfall over New England including Boston where they’ve officially broke their 1995-96 record for […]
You have to go back to November for the last time the NAO went negative but for a brief few days this week, it’s back negative. This is a superb upper air pattern for cold to get delivered into the UK from Siberia. One big problem, there’s NO truly cold continental air to get pulled in […]
No question, it’s been mild to warm on the East Coast with snow cover shrinking rapid. However, the cold pattern is coming back and here’s why. When you’ve got a strong phase 7 MJO, and the AO/NAO are heading into negative territory with abnormal warm water up the West Coast, you just know where the heights […]
Both atmosphere and ocean over the Pacific are showing signs of a strengthening El Nino (finally). There also appears to be a trend more and more towards a stronger El Nino as we head through summer into next autumn. While I would take this somewhat with a pinch of salt as models have frequently showed a stronger nino only to have […]
As warmth tracks northward this week, so snow pack warms and melts further. The deep Northeast snowpack is fair getting chipped away from the ‘southern edges’. All the yellow area is where the model sees snow gone by 48 hours. Still over 40 inch depths up in Maine. [s2If current_user_can(access_s2member_level1)] Flooding Rain Potential 30 Above […]
The wind stream map off MeteoEarth shows just how busy the North Atlantic is today. Four lows are spinning and three are producing hurricane-force gusts. It’s all eyes on the high building and expanding over Scandinavia as this will turn our flow easterly over the next 24 hours. These chilly easterly winds will pick up […]
