A strong cutoff upper low establishes over the Iberian peninsula and western Mediterranean this weekend. It brings colder and more unsettled weather to the region, with heavy rainfall and snowfall as well as some thunderstorms. Strong precipitation, mostly rainfall at lower elevations, begins today as the cold front passes across the peninsula. Peak totals are expected over northern and northeastern Spain, where high-resolution models indicate up to 70-130 mm of precipitation (rainfall or equivalent snowfall), locally possibly more. At higher elevations, up to 50-60 cm of snow is expected, although most areas will receive significantly more, up to to about 10-20 cm. The snow limit will be at 2000+ m ahead of the cold front, but will rapidly drop throughout
The progressive pattern with numerous successive lows over western and central Europe gives way to one last major trough pushing into W Europe and forming a powerful rex block during the weekend and early next week. A deep trough advances across the eastern Atlantic over the Iberian Peninsula today, with its associated frontal system producing quite significant amounts of precipitation. A cutoff upper low forms over the region by mid-Saturday, centered over the central Iberian Peninsula. Persistent precipitation is expected to produce to 30-50 mm rainfall (or corresponding snow) and up to 100-150 mm in the extreme N-NE of the country by the end of the weekend. Thunderstorms may be expected along the frontal system as it moves across the
STORM SURGE advances on Salem, MA lighthouse during high tide, with feet of coastal flood waters and massive chunks of ice covering the entire pier in a matter of minutes. Now, flood waters left behind are freezing as storm moves northeast. #Blizzard2018 @breakingweather pic.twitter.com/XxO0VMpLzF — Reed Timmer (@ReedTimmerAccu) 5 January 2018 It appears the storm has made "landfall" near Saint John, New Brunswick.

A rather classic but a very impressive winter storm – a so-called Nor’easter is moving along the US east coast today and is bringing powerful winds along the coastal areas as well as intense snow blizzard conditions inland across the NE states. Currently at a mature stage, the cyclone has already deepened below 960 mb, very low for any winter storm! The name Nor’easter comes from the direction of the strongest winds, northeast to southwest in the NW quadrant of the cyclone, where blizzard conditions occur. A Nor’easter develops when deep troughs from the Arctic travel across eastern Canada and advect very cold airmass onto the Atlantic along the east coast, where the main channel of Gulf Stream is located.
Severe snowy weather in winter or extreme rains in summer in the UK might be influenced by warming trends in the Arctic, according to climate scientists in the US and the UK.
Large areas of Earth's surface are experiencing rising maximum temperatures, which affect virtually every ecosystem on the planet, including ice sheets and tropical forests that play major roles in regulating the biosphere, scientists have reported.
A new report calls for an international, multi-institutional comprehensive campaign of research, observation, and analysis activities that would help improve understanding and prediction of the Gulf of Mexico's Loop Current System (LCS). The position, strength, and structure of the LCS -- the dominant ocean circulation feature in the Gulf -- has major implications for oil and gas operations, hurricane intensity, coastal ecosystems, oil spill response, the fishing industry, tourism, and the region's economy.
Humans may be the dominant cause of global temperature rise, but they may also be a crucial factor in helping to reduce it, according to a new study that for the first time builds a novel model to measure the effects of behavior on climate.
