You know it's been a shithouse crummer when even the media, BUM and Weatherzone not only don't put out their usual "hottest summer on record" spiel at the end of the season, but actually go the other way! Edit - oh wait never mind, they still managed to shoehorn some global warming malarky in there. They are smart, '61-'90 "averages" means every year can be above avg  The POR they use for averages doesn't matter, the trend is clear regardless. |

Poor alex992 & tommyFL; Florida is one of the only regions in the U.S. to have had an above average February. |

"did not participate in winter" not sure what that guy is talking about. Could have looked back to a below-average December and near-average January to see that wasn't the case. Also, he's actually using that garbage PRISM for anything? Another sad case of the Twitter climatologist. Remind me to disregard anything he says in the future.

impressive forecast from the Mount Washington Observatory
A cold front swept through the region this morning, shifted winds westerly, and began to introduce a much drier and colder air mass from aloft and over Canada. The upper level Low will pass overhead tonight starting this evening and will exit overnight through the morning. Pressure will continue to fall this evening to levels uncommon at this elevation and as a result, the air mass and flow will originate from aloft and descend down. This will cause temperatures to fall to around 20 degrees below 0, and also cause wind speeds to accelerate as air rushes down to fill in the low pressure. Winds are already sustained in the hurricane-force territory and will increase through the night. As the low moves east, pressure gradients will increase with from their already elevated status. Winds will increase to become sustained around and over the century mark with gusts potentially reaching 150 mph Tuesday morning after sunrise. Gusts will likely max out around 140 mph, but an outlier gust will be possible given the gravity and pressure-driven nature of flow behind this Low. Winds sustained around 100 mph and air temperatures falling to lower than 20 degrees below 0 will send wind chills to around 70 degrees below 0. Higher gusts will force wind chills slightly lower as well. Any exposed body parts will likely develop frostbite in minutes. As the upper-level low exits Tuesday, temperatures will start to rise into the afternoon hours. Having said that, winds will remain elevated through Tuesday and Tuesday night with continued gusts over 100 mph. During the acceleration and fall of temperatures, there will be a continued chance of upslope snow showers. It is likely that higher summits will remain in the clouds through Tuesday morning with only the peaks in the fog as descending dry and cold air undercuts surface moisture and rises up to summit level, condensing at the summits. Temperatures will rise to around 10 degrees below by the evening time and will continue to rise to around 0 degrees by Wednesday morning. The higher summits should be in the clear during the evening hours, but a weak disturbance will slide through overnight and into Wednesday morning.

I could be wrong here but I thought PRISM was just an interpolation/extrapolation system. You can't make climate maps without interpolating/extrapolating the areas between stations. |

I could be wrong here but I thought PRISM was just an interpolation/extrapolation system. You can't make climate maps without interpolating/extrapolating the areas between stations. You're absolutely correct, but interpolation accuracy is not particularly important when making maps at a national scale since locations with data are plentiful. What makes PRISM so terrible, however, is its simulated normals and monthly data. It allows you to find interpolated "averages" for any point in the country. The problem is it seems to not take local geography into account at all beyond very basic stuff like elevation. According to PRISM, some mountain tops will have absolutely ridiculous diurnal ranges which are completely impossible. I'm sure the map is fine at this large of a scale, but if you really zoom in to areas with varied terrain, it will be completely wrong. |

I feel like most countries have a similar system, seems odd to completely discredit maps based on PRISM when most weather maps in most countries probably are based on a similar system. |

nasty cold arctic air blew in; strange one-day arctic outbreak, tomorrow will be back to normal though end of the week looks chilly but not extreme. High of 19ยฐF today, 17ยฐF below average

really fast drop after sunset; dews down to -10ยฐF. Winds up to 40 mph   Mount Washington reached a wind chill of -80ยฐF, doesn't happen most years  |

Very warm today, high was 66 (19 c) after a 20 f (-7 c) low.
Dews were in the single digits f so quite dry too.

Here we go, high of 0C today and then everyday in the upcoming week has a forecast high above freezing, with several days above 5C The first week of March is often still in full winter mode, so this is a pleasant start to the month. I hope it persists and that the rest of it doesn't turn back into winter. |
