Area Forecast Discussion National Weather Service New York NY 920 PM EST Mon Jan 27 2020

SYNOPSIS. A series of upper level disturbances move across the region through Tuesday night. A cold front will also pass through the region Tuesday evening. High pressure will then gradually build through the end of the week. Low pressure may pass just offshore this weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Raised sky percentage forecast based on trends, and delayed any clearing later tonight. Any clearing may occur behind shortwave and associated PVA that pivots east overnight.

Cloudy conditions have resulted in warmer temps, so update to temperatures were made as well.

Lows will range from the upper 20s inland to the lower 30s at the coast. These values are 5 to 10 degrees above normal.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. The upper low slowly moves towards the North Atlantic within a larger mean upper trough over the Canadian Maritimes. Another 500 mb vort max/shortwave will swing southward towards the local area during the day on Tuesday. This shortwave will send a cold front through the region late in the day. The energy and shortwave should move through the region in the evening. The day should start out mostly clear to partly cloudy and then clouds increase in the afternoon as the shortwave nears. No precipitation is expected with the cold front passage. Highs on Tuesday will continue above normal for this time of year in the lower and middle 40s.

The cold front and shortwave move offshore Tuesday night with high pressure building to the west. Clearing skies are anticipated and cooler air advects into the area under NW flow. Lows should be closer to normal in the lower and middle 20s for most locations except NYC where temperatures fall to near 30 degrees.

LONG TERM /WEDNESDAY THROUGH MONDAY/. High pressure will keep dry conditions across the region through the end of the week with seasonably chilly conditions. Expect highs in the 30s or lower 40s through this period and overnight lows in the teens and 20s.

There is the potential for a coastal low to impact the region next weekend. Models are still struggling to key in on the track of this low, therefore will continue to carry chance POPs for Saturday and Sunday. We will continue to closely monitor trends in the guidance as we get closer to the event. Temperatures during the weekend will be in the 40s with lows in the upper 20s to low to mid 30s. Dry conditions are expected at the start of the week.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. Low pressure over the Canadian Maritimes moves slowly east as a large area of high pressure gradually builds in from the west. This will keep the area under a NW flow.

VFR. Bkn-ovc clouds 4-6 kft should scatter overnight before bkn-ovc clouds redevelop again Tuesday late morning/afternoon.

W/NW winds prevail 10 kt or less overnight. Speeds increase slightly after 14-15Z Tuesday, and a few gusts 15-20 kt is possible during the afternoon.

OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY. Tuesday night. VFR. Wednesday through Friday. VFR. Saturday. MVFR or lower possible in rain or snow.

MARINE. Will allow the SCA to expire as seas subside, and winds remain just below 25 kt criteria. The sub SCA conditions are expected all waters through Wednesday, and should diminish further Thursday and Friday. The next chance of SCA conditions should be over the weekend with the potential of a coastal low impacting the waters.

HYDROLOGY. No hydrologic impacts are anticipated through the end of the week.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
