Spring 2015
Through the weekend, cold, dry arctic air has been filtering south over the UK and Ireland. Thanks to clear skies and light winds, temps dropped to surprisingly low values early Monday morning. [s2If current_user_can(access_s2member_level1)] The mid-winter -8.0C at Katesbridge, Co Down was the coldest April night on record for the site and came close to Northern Ireland’s April record of -8.5C […]
It’s was a clear, cold start to Sunday with rural frost around. I was out early and had to scrape the wind screen. [s2If current_user_can(access_s2member_level1)] Once the sun begins to warm the lower levels, we raise the lapse rate or temperature difference with height as colder air is back. Since yesterday’s post, a frontal zone […]
I stand by the idea that April’s final week and May’s opening week is cool with a major storm threat on the East Coast. That very system could be responsible for recasting the upper atmospheric pattern and allowing the first real surge of ‘summer warmth’ into the Northeast and Mid-Atlantic. New York has managed to […]
Gone is our beloved high pressure pattern and back is the cool, unsettled trough. Going by multi runs of the GFS operational, ensemble, ECMWF and CFSv2, it appears this pattern is a true flip that’s here to stay. Certainly through the first half of May. Be sure to watch today’s video for the discussion. [s2If […]
For the past several days, the models have hinted at a fairly major storm system developing over the Southeast and riding up the East Coast at the close of April/beginning of May. While there’s a lot of uncertainty and it’s still a long way off (some 6 days out), based on current projections, this could […]
You’ll notice the difference out there today as patiently waiting weather systems begin to move in. Why such a change? We’ve lost over 24mb in pressure and so there’s no resistance in holding back surrounding weather. Today marks the change with cloudier skies and some shower activity but it’s not till Saturday that the atmosphere […]
A couple of weeks ago I was leaning towards a warmer than normal May but as we progressed through this month I began to think twice. Based on several factors including the strong Alaska to Greenland block we’ve got going and will continue to drive a chilly, wet pattern for much of the US as we end April and […]
Plenty of west-east movement in the US weather pattern next 10 days with rumors of big east coasts storms. We shall see. [s2If current_user_can(access_s2member_level1)] Here’s the ECMWF 7 day snow. 10 day Moral is, there’s plenty of fun and games in this pattern still.

The unusual deep, cold upper vortex drifting down over the Great Lakes bringing an abnormal chill from the Upper Midwest to Mid-Atlantic may not be a short lived blip but part of a pattern that lingers. For the first time since last year, the NAO is tanking and that means a twin trough under Greenland […]
