(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kgyx 221341 afdgyx area forecast discussion national weather service gray me 941 am edt Thu aug 22 2019 Synopsis A cold front will sweep across the region today accompanied by scattered showers and thunderstorms. A few thunderstorms could contain strong gusty winds. Cooler and less humid air follows the front beginning tonight. High pressure will gradually build in over the weekend and early next week allowing for an extended stretch of quiet weather. Near term until 6 pm this evening 930am ... Adjusted current temperatures and cloud cover. Some low clouds hanging on in the midcoast, but expect them to continue to erode. For the afternoon increased the pop slightly. Expecting a line of showers and thunderstorms to move through which will impact most areas for a brief period of time. 605 am... Minor estf update to reflect the current mesonet in near term grids. Prev disc... at 06z... A 1003 millibar low was over quebec with a wavy warm front through northern new england and a trailing cold front through the lower great lakes. NWS doppler radar mosaic showed scattered convection occuring along and ahead of the boundary. Widespread stratus and fog had formed across much of the area and should gradually lift and mix out as the warm front pushes to our north in a strengthening southerly flow ahead of the cold front. Sunny periods and southerly flow should warm temperatures into the lower and mid 80s across much of the area ahead of the cold front. Dew points in the 60s and lower 70s combined with forecast high temperatures should yield capes between 1000 and 1500 j kg. Modified forecast soundings support a few broken line segments with strong wind gusts the primary threat with late morning and afternoon convection. By early evening the front and much of the convection will have exited the coast. Short term 6 pm this evening through 6 pm Friday For tonight... The front will be just offshore and a weak wave traveling along the boundary. This will slow post-frontal clearing along the coastal plain and could brush seacoast new hampshire and southwest coastal maine with a few showers overnight. Elsewhere... A partly cloudy night with patchy valley fog and stratus developing in the predawn hours. On Friday... The front pushes well offshore with sunshine for the coastal plain while northern and mountain sections see a few more clouds with the upper trough and a passing impulse. Comfortable dew points and a westerly breeze will make for a fall-like feel as high |
temperatures are limited to near 70 in the mountains and in the 70s elsewhere. Long term Friday night through Wednesday In the long term high pressure will build overhead keeping the forecast area under rather pleasant conditions. However by Sunday models are showing an upper level closed low developing and moving slowly northeast Sunday through early Tuesday. The overall position of this closed low will ultimately determine the location of afternoon clouds and showers for Sunday and Monday. I have a 20 to 30 pop over the southern half of the forecast area for Sunday into early Monday. The chance for showers could linger into Monday afternoon or even early Tuesday depending on how fast the low departs. For now think the best chance for any widely scattered shower will be Sunday. Other than this the long term looks cooler than normal Saturday through Tuesday then above normal Wednesday and Thursday. Dewpoints start to rise Wednesday as does the chance for precipitation as a cold front approaches the area. Aviation 14z Thursday through Monday Short term through Friday ... Areas of ifr and lifr through 12z in stratus and fog. ThenVFR with sct MVFR developing in -shra -tsra ahead of a cold front. Sct MVFR tonight in CIGS with lcl ifr in valley stratus and fog. Improving toVFR throughout aft 12z Friday. Long term... MostlyVFR. Marine Short term through Friday ... Winds will pick up later today and this evening with the cold frontal passage but both seas and wind gusts should remain below SCA threshold. Long term... Winds and seas should remain below SCA criteria. Gyx watches warnings advisories Me... None. Nh... None. Marine... None. Synopsis... near term...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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. |
