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 […]

Thanks to a powerful 1052mb high spinning over Scandinavia, Mother’s Day 2015 is looking mostly cloudy (but with some bright or sunny spells), breezy, if not windy and chilly with our air originating all the way from Russia. There’s a chance of some shower activity pretty much anywhere. Here’s how the GFS surface chart looks at 12z tomorrow. Easterly […]
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 […]
