758 pm edt Fri may 26 2017

The low pressure system that brought all the rain to the north
country over the past 24 to 36 hours continues to move eastward.

This will allow showers to come to an end tonight... But plenty of
cloud cover will exist. Areas of fog are expected to develop as
well. Otherwise... The news is good with respect to the memorial day
weekend as dry weather is expected for Saturday and Sunday along
with a warming trend. At this time it does look like showers will
return to the area late Sunday night into memorial day.

Near term until 6 am Saturday morning
As of 645 pm edt Friday... Minor update to match current
observational trends and to align pops more in tune with most
recent hrrr btv 4km WRF output through the midnight hour or so.

This continues to suggest a gradual tapering off of showers this
evening, leaving a largely dry forecast later tonight. Did opt
to confine threat of fog across mainly the western dacks into
the slv overnight where lighter low level wind profiles exist
and some partial clearing may arrive in the pre-dawn hours. The
rest of the forecast remains on track and unchanged. Have a
great evening.

Prior discussion...

upper low in the gulf of maine late this afternoon will
continue to move eastward tonight. This will help to bring
showers to an end later tonight... But based on satellite imagery
see no reason why we do not stay cloudy all night. Plenty of
low level moisture will exist and cannot rule out the
development of some fog and have included in the forecast for
later tonight... Mainly after midnight. Lows tonight should be in
the mid 40s to lower 50s.

Short term 6 am Saturday morning through Sunday night
As of 328 pm edt Friday... The bottom line is we are looking at
a warming and drying trend Saturday into Sunday. We should still
see plenty of clouds around through mid-afternoon on Saturday
before more noticeable clearing finally takes place. This will
temper highs just a little with readings in the mid 60s to lower
70s expected. Despite the clouds no precipitation is expected.

The dry weather continues right into Sunday as upper ridge
builds into the region. Looking for more sunshine than Saturday
and even warmer temperatures with highs generally in the 70s. No
precipitation is expected.

The pattern will change Sunday night as upper trough moves toward
the region. Clouds will be on the increase along with increasing
chances for precipitation... Especially after midnight. The clouds
and precipitation in the southwest flow will help keep low
temperatures up with lows in the upper 40s to upper 50s.

Long term Monday through Friday
As of 328 pm edt Friday... Unsettled period starts with a
surface low pressure system over eastern ontario bringing a
frontal boundary through the north country on Monday. Showers
and possible thunderstorms will accompany this front along with
cloudy skies. The surface low is associated with a 500mb closed
low that will sit over the northern great lakes region through
mid-week, with several areas of vorticity rotating about it.

This will provide the north country with several bouts of rain
showers and possible afternoon thunderstorms.

On Wednesday, most GFS and ECMWF show the 500mb low shifting east
into quebec and weakening. This will provide widespread
precipitation with another chance for thunderstorms for portions of
the north country. A few more shortwave troughs will affect the area
through the rest of the work week.

In summary, there will be several chances for rain showers and
possibly a few thunderstorms. There will be breaks in the showery
activity and even breaks of sunshine from time to time. Seasonable
temperatures expected for this time of year. Daytime max
temperatures will generally stay in the 60s to low 70s and min
temperatures will range from the 40s to mid 50s.

Aviation 00z Saturday through Wednesday
Through 00z Sunday... Complex forecast with variable conditions
through the next 24 hours. Mostly MVFR CIGS with light rain
showers this evening. Periods of ifr CIGS expected at kmpv,
krut, and kslk during the early evening.

Kmss is expected to improve with CIGS lifting toVFR early in
the evening and showers coming to an end. However, these
conditions will also help ifr fog and CIGS to develop around 08z
through mid morning, before improving toVFR after 12z

Kslk with MVFR CIGS will deteriorate overnight to ifr CIGS and
further deteriorate to lifr vlifr around 08z through sunrise.

Fog will erode during the morning hours, eventually improving to
vfr conditions in the afternoon.

Kpbg will fair better than most other sites as NW flow remains
a little stronger with predominantlyVFR conditions and periods
of MVFR CIGS this evening.VFR conditions continue during the
daytime Saturday.

Kbtv experiencing MVFR conditions with brief periods of
improvement and deterioration early this evening. Expect MVFR
cigs to be the predominant conditions through at least late
Saturday morning. CIGS expected to lift toVFR in the late
morning early afternoon.

Kmpv expecting MVFR CIGS with periods of ifr for the first half
of tonight. Conditions expected to improve toVFR Saturday

Krut will be similar to kmpv with MVFR CIGS seeing periods of
deterioration to ifr this evening before improving toVFR during
the late morning midday timeframe.

Winds generally out of the NW but remaining light overnight.

Wind speeds will pick up to 4-8 kts during the day.

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 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.
