September weather discussion

[dendrite]

Some of these cold shots have tempted me to put the heat on at night so I'm fine with these boring 70/45 days this time of year. As long as it isn't 90/65 I'm happy. The foliage is loving these diurnal ranges too.

[forkyfork]

Winter wasn't cold

this. wasn't it above normal for a week after the blizzard?

[CoastalWx]

Until we change the hemispheric pattern, it's more of the same. The only semi-interesting feature I see is a potential tropical in the gulf. The GFS wants to inject moisture up the coast.

this. wasn't it above normal for a week after the blizzard?

Real winter weather last year occurred between Jan 21st and March 22nd with between 40- 60 inches of snow in that period with temps running -2 below normal, great snow cover, perfect winter conditions.

It was cold immediately after the greatest blizzard since 1978 with a couple of days of very low 40s one day that tickled 47 with snow 7 out of these days falling

no extreme warmth or cold, upper 70s then lower 70s dry as a bone

 

[OceanStWx]

Some years it is and overall the entire year has generally followed that pattern. Deep cold snowy winter quickly turned warm in April and we got right into deep summer in a May, while June turned wet and deep dews and the hottest July in all of SNE history quickly turned milder in August and Sept quickly turned cool and below normal with an early leaf change.

 

Still think this may be a better example for a hot July, as far as sensible weather is concerned. Really roast the Tarmac.

Wow, I didn't realize you guys had 5 straight days of 40F or higher following the Blizzard, especially with two days that had lows of 34F and 31F, thats like a 48 hour melt.  It seems like that happens a lot these days.  Whatever happened to the like week of teens following a blizzard?  Fluffy snow piled high and not allowed to rot, drip, and blacken along the sides of the roads.

that was BDL, lol snow depths were greater here in Feb than anywhere in northern NE, it also snowed on 7 of those 11 days my friend

That happens quite a bit because of regime changes following these big storms. Large cutoffs will ultimately fill in and flood New England with milder maritime air. Or, some of that warmer air over the west and Rockies moves east following a large event. It doesn't always happen, but there are reasons why it does.

[CoastalWx]

Feb snow melted down fairly quickly.

That doesn't happen in Connecticut. A week of teens? We're lucky if we get a couple of those days per year (the average is right around 2-3). It's not exactly a cold weather state, and February averages 10-14 days with highs 40+ and 2-4 days 50+, so you're bound to have lots of days of melting if you get snow.

You do generalize CT quite a bit, NW CT and SW CT are different climates. Jan 11 after the 21st storm was in the teens for five days in most of NCT with a tickle of low 20s

[weathafella]

I see Powder's point. I remember many a big snow event growing up followed by windy and very cold for a week. In fact, the JFK inaugural storm was part of a big push of cold that held for over 2 weeks bookended by the JFK event and the 2/3-4/61 bomb. The February 61 huge snow ushered in the new warm pattern.

We have a lot of 6-12" events that usher in cold behind them, but it's not a surprise why see sometimes see milder patterns (not torch) post meteorological bombs.

Hey I gave a range which roughly represents the normal interquartile range which by definition will not include the coldest (NW) and warmest (SW) sites. If you wanted to show climate with respect to what people experience, then CT would look a lot warmer because SW CT would have a large weighting. Climo is climo for a reason, and our winters are far from bitterly cold with highs 40+ 1/3 to nearly 1/2 of winter days.

Feb snows always seem to melt quickly even with Arctic pushes, just a function of dew points and sun. Best times for severe cold and snow retention run from Christmas to Groundhog day

Jan 2005 cold post bomb was aided by a nice east based -NAO that occurred.

Big difference between that doesn't happen and its not common, its not common in Stowe Vt either at the valley. A week of teens after a huge synoptic storm is pretty rare unless you are above 2K

you clown.

 

I grew up near Albany... plenty of storms were followed by lots of cold weather.  I'm thinking like storms that depart and leave behind a week of LES out in western NY and the windy, flurries amid partly sunny skies.

[powderfreak]

We have a lot of 6-12" events that usher in cold behind them, but it's not a surprise why see sometimes see milder patterns (not torch) post meteorological bombs.

 

Yeah it makes sense... the Archembault (SP?) events that switch from -NAO to +NAO are the whoppers that tend to fill in behind them.

 

Your idea of 6-12 inch events seems spot on in terms of strong CAA on the backside...maybe even 18-inch events.  Above 18-inches we probably get into that Hemispheric pattern change type event.

I don't think it is, well maybe a full week of not getting higher than 19F... but trust me, in Jan and Feb we get plenty of cold following snowstorms.  Sometimes too cold.  That's usually when our lowest temps of the season are achieved in the valley.

 

I'm sorry and didn't mean to piss off people by that comment and make folks defensive...it wasn't to offend folks that it got warm.  I just didn't realize or I forgot it was a mild-up that quickly after the storm.  It got mild up here after a couple days with lows or zero or below.

[forkyfork]

it didn't break 40 in boston until 8 days after the 1978 blizzard

[powderfreak]

Looking at the days following the February blizzard, it was very cold up here following it and then it did warm-up quickly.

 

The MVL lows following that storm on the 9th-11th were 4F, -14F, 0F but then on the 12th we had a 36/31 day followed by two 34/24 type days.  So yeah, that's pretty warm (+12 departures).
