9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed. Please report errors HERE or send an email to me at L-36.com. Allen |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kokx 202348 afdokx area forecast discussion national weather service new york ny 748 pm edt Fri sep 20 2019 Synopsis High pressure will dominate through the weekend. A cold front approaches on Monday and moves through Monday night. High pressure follows for the midweek period, then a weakening cold front approaches late in the week. Near term until 6 am Saturday morning Forecast remains on track, with favorable radiational cooling conditions expected into the night. Temperatures in outlying, more rural areas have already decreased quickly with the loss of diurnal cooling. Will lean toward cooler guidance. However, lows will still average a degree or two above normal. As for sensible weather, valley fog is possible once again late at night. There is a high risk of rip currents at the atlantic ocean beaches into this evening due to long period easterly swells. Short term 6 am Saturday morning through Saturday night Large ridge remains in place. With westerly flow around sfc high that is centered to our south, and expected temps at the top of the mixed layer around 16-17c, forecast high temperatures should rise into the 80s under a good deal of sunshine. Temperatures Saturday night will once again average above normal, with a range from the lower 50s interior to mid 60s in nyc, quite a spread between radiational cooling locations, and urban heat island effect. There is a high risk of rip currents at the atlantic ocean beaches on Saturday. Long period swells lessen as the day progresses, so conditions may improve late in the day. |
Long term Sunday through Friday High pressure will be centered to our south over the western atlantic on Sunday. A return SW flow and 850mb temps at around 15c will allow for highs above normal across the forecast area. Highs generally in the 80s except for eastern LI and SE ct, particularly along the coasts. A longwave trough shifts through the great lakes on Monday and moves into the northeast Tuesday. This will send a cold front through the area Monday evening. There will be a chance of showers in the afternoon into the evening ahead of the front, then chances drop off during the overnight hours. Have added a slight chance of thunder for some areas as capes of a few hundred j kg are forecast by some models, combined with some shortwave and jet streak lift. High temperatures on Monday will once again reach the 80s for most areas. High pressure then keeps us dry Tuesday and Wednesday along with high temperatures closer to normal. A cold front associated with low pressure tracking through southern canada then approaches on Thursday. The upper flow is progged to be more zonal than cyclonic, so the front therefore weakens as it approaches us. Will still go with a slight chance of showers with this front for Thursday. High pressure builds back in on Friday with dry weather. Aviation 23z Friday through Wednesday High pressure remains across the region through the TAF period. Vfr. Winds becoming light W NW late tonight into morning push, then backing SW in the late morning. Afternoon coastal sea breezes are expected for S coastal terminals, and possible into nj terminals.

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 numerious 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. |
