2/23 AM All Zones: Morning Clouds & Fog, Then More Warmth This Afternoon

Some low clouds and patchy, dense fog this morning should gradually clear out for more sunshine this afternoon. An unseasonably warm airmass will still be over the region, Southwest winds will help temperatures rise well into mid-upper 60s over much of New Jersey, Lower Hudson Valley and immediate NYC metro area by mid-late afternoon. Temperatures might be cooler in the mid-upper 50s to lower 60s in more coastal areas like Long Island and Connecticut coast, with winds more ocean keeping more low clouds and fog linger into the afternoon hours.

2.22 PM Zone Update: Record-breaking warmth on the way

As a trough digs into the West Coast of the United States over the next 24 to 48 hours, a ridge is forecast to develop throughout the Central and Eastern United States. Southerly winds in the mid and low levels of the atmosphere will aid in the ridge moving northward and expanding, with anomalously warm air surging northwards from the Southern and Central US into the Eastern United States by the latter half of this upcoming week.

While the ridge is impressive in the mid levels of the atmosphere, the surface temperature response will be even more impressive. Temperatures on Thursday and Friday afternoon, throughout the Northeast (and especially in the interior) will average 20-30 degrees above normal averages for this time of year. In many areas, this will mean afternoon high temperatures in the 60’s and possibly even lower 70’s!

Dense fog takes over NYC, in photos

The story of the morning, undoubtedly, was the development of dense fog which initially began in only patchy areas of the suburbs early this morning. But by sunrise the fog had lowered and thickened, in addition to spreading throughout the area — including into lower manhattan. The sunrise and aforementioned development of dense, low fog created a terrific (and somewhat rare) picture opportunity as the tops of building and bridges stuck out of the low cloud deck.

Often misunderstood, fog forms as water vapor condenses into tiny water droplets in the lower levels of the atmosphere. Fog is not water vapor itself (Water vapor cannot be seen), nor is it “smog”, a variation of the word which is used to describe lowered visibilities that occur as a result of pollution. But this morning was a more classic case of low fog, more typical in London or San Francisco. The occurrence was a terrific photo opportunity for some of New York City’s best photographers (and webcams). We’ve included some of the best shots below.

The National Weather Service continues a Dense Fog Advisory through noon today, and also urges caution for those who are traveling. Visibilities near zero are possible in some areas, and the fog is expected to cause delays not only on the roads but also at the area airports. The fog is expected to lift by this afternoon, with a chance of scattered showers and high temperatures generally in the mid to upper 40’s.
