NYC Weather Update – Sept 17, 2014

NYC, Weather Update, Weekend, , , , , ,

It’s going to be a quiet weather week after the rain that passed yesterday. For the remainder of the week, high pressure will keep conditions fair and sunny, despite the passage of a weak cold front tomorrow. Temperatures today and Thursday should be in the mid-70s. There will be a slight cool-off Friday after the passage of that weak cold front, but things will warm back up this weekend.

Saturday – high temperatures will be in the mid-70s, partly cloudy skies.

Sunday – a warm front will pass through early Sunday and allow for temperatures to climb to about 80. Clouds will increase as a trailing cold front approaches. No precipitation forecast at this point, but I wouldn’t be surprised if there were a couple light showers with this front.

Get ready for the official start of autumn! Monday marks the autumnal equinox, the point at which night and day are about equal in length. From here on out, our days will be getting shorter and shorter, so try and get out there to soak in some rays and get some vitamin D in you.

NYC Midweek Weather Update – Apr 23, 2014

NYC, Rain, Weather Update, Weekend, , , , , , ,

You can feel that cold front has passed, can’t you? A stiff northwest wind is ushering in an unseasonably cool air mass, and temperatures will be quite a bit lower than yesterday, with high temps about 10 degrees less than yesterday in the mid-upper 50s. Cloud cover should continue to diminish throughout the day.

Windy and cool weather persists Thursday – with high temperatures again struggling to hit 60. The breezy conditions and very dry air mass in place will lead to conditions conducive to the spread of wildfires.

Our next shot of rain comes Friday, with a weak low pressure system moving over the Great Lakes and a trailing cold front. Forecast models suggest the system weakens as it approaches, hence lowering the chances for rain. If it rains, only light, showery precipitation is expected. High temperatures Friday will be slightly warmer, in the low 60s.

Saturday & Sunday – So far, we have a nice weekend on tap with mostly sunny skies and temperatures slightly below average in the low-mid 60s both Saturday and Sunday.

Really Cool Graphic – Frozen Great Lakes

Cool Images, Outside of NYC, , , , , , , , , ,

It may be spring now, but it certainly doesn’t look or feel that way for the Great Lakes, most of which are still ice-bound. Superior, Huron, and Erie are still almost entirely covered by ice, while Michigan is less than half covered. The only lake not ice-bound this winter has been Ontario at the far-right. Image from LANCE MODIS taken on March 16th.

You may be wondering why Lake Ontario is the exception to the frosty rule here. Ontario’s average depth is about 283 feet, only Superior has a greater average depth (Erie is the shallowest, so even though it’s further south than Ontario, it’s often the first to freeze). Furthermore, Ontario is located at a lower latitude than Superior and Huron, and it’s relatively smaller surface area maximizes its heat retention.

Really Cool Graphic – All Reports of Severe Hail from 1950-2013

Another neat graphic from Storm Prediction Center’s SVRGIS: all reports of severe hail over .25″ in diameter from 1950-2013! Again, note the relative scarcity of severe hail west of the Rockies, but look at the density of hail reports over Mississippi and Georgia. Also, check out the dense patch of hail reports just east of the Front Range in Colorado.

Really Cool Graphic – Tornado Tracks from 1950-2013 Mapped

Climate, Outside of NYC, Tornadoes, , , , ,

Just a super interesting graphic that the Storm Prediction Center put together using GIS data. What you’re seeing is a graphical representation of the track of each tornado that’s impacted the continental United States from 1950-2013. Notice the density in Tornado Alley, a region of the country where geography is conducive to the large scale weather patterns that produce tornadoes. Also, check out the general trend of a northeast vector to the tornado tracks. Lastly, note that although tornadoes are considerably less common in the Northeast, they still do occur with some frequency.
