Marine Weather and Tides
Milton, VT

Version 3.4
What's New / NOTES
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

254 pm edt Sun apr 22 2018

High pressure will dominate regional weather conditions through
Tuesday with fair weather and a long awaited return of warmer
temperatures. The next chance of rainfall occurs by Wednesday
into Thursday of next week as low pressure tracks through the

Near term through Monday night
As of 254 pm edt Sunday... Pleasant and dry weather continues
through Monday night as deep layer high pressure builds atop the
northeast. Outside some filtered high clouds drifting into the
area later Monday night clear skies are expected through the
period. Lows seasonably cool once again tonight given ample
radiative effects under a dry ambient airmass - mainly 20s to
lower 30s. By tomorrow 925-850 mb thermal profiles warm further
supporting mid-afternoon highs from the upper 50s to lower 60s
in the mountains and lower to mid 60s in valley locations. Winds
should trend light southerly over time as the center of the
surface high edges east so just an outstanding spring day to
start the work week. Fair and dry weather continues for Monday
night under continued light south southwesterly flow. A little
more variability is expected in overnight temperatures with
eventual readings hinging heavily on the degree to which the
nocturnal boundary layer remains mixed. For now have offered in
the upper 30s to lower 40s in the st. Lawrence and champlain
valleys with values ranging through the 30s elsewhere.

Short term Tuesday through Wednesday
As of 233 pm edt Sunday... Well our nice period of weather will quickly
come to an end on weds with anticipated widespread rain event
and cooler temperatures. However still expecting increasing
mid upper level clouds late Tuesday with temperatures climbing
well into the 60s on developing south winds. The combination of
mid upper level ridge overhead and deep dry layer in place
especially thru 18z should produce plenty of Sun in the morning
on Tuesday. Progged 850mb temps near 5c with good mixing and
adding 15c gets btv around 20c for a high on Tuesday. Thinking
near 60f slk nek to near 70f cpv... With slightly cooler values
south because of clouds developing. Tuesday will stay dry as
leading edge of precip will fall as virga due to very dry low

By weds... Southern stream short wave energy and associated deep
moisture overspread our CWA from south to north. Pws surge near 1.0
as 1008mb low pres tracks from va beach at 09z weds to portland
maine by 06z thurs with pres near 1000mb. This track combined with
some northern stream short wave energy will produce a widespread
rainfall across our on weds into Thursday. Given the available
moisture and forcing and favorable track of sfc low pres... Thinking
qpf will range between 0.50 and 1.0 by thurs. Temps will struggle on
weds with clouds precip... Thinking heaviest precip arrives toward
18z... With highs only in the mid 40s to lower mid 50s. Will trend
pops toward 100% on weds, based on high confidence it will rain and
measure by 00z thurs.

Long term Wednesday night through Saturday
As of 233 pm edt Sunday... An active period of weather is expected
as mid upper level trof redevelops across the great lakes into
the NE conus. This general synoptic scale setup will support
above normal precip and below normal temps for days 4 thru 7.

Closed 5h and 7h circulation slowly lifts toward northern new
england by 12z thurs... As moderate low level cold air advection
develops on brisk 850mb winds of 30 to 40 knots. This helps to cool
925mb to 850mb thermal profiles below 0c by 06z thurs dacks and 12z
northern central green mountains with favorable 1000 to 700mb
moisture. Soundings show freezing levels dropping to near 2000 feet
by 12z Thursday... Supporting some snow and potential accumulations
in above 1800 feet on thurs morning. Best chance for a wet snow
accumulation would be northern dacks and from mt mansfield to jay
peak in the central northern greens. Otherwise... A cold rain
continues for the valleys with lows on thurs morning in the mid 30s
to lower 40s. Mid upper level trof and associated surface low pres
lifts toward northern maine by 00z with quickly drying profiles aft
18z. Thinking clouds precip start the morning... With some Sun and
warming temps in the aftn... Based on latest trends.

Late week into next weekend uncertainty increases with magnitude of
mid upper level trof and potential of another area of low pres
impacting our fa. Gfs ECMWF differ on depth of mid upper level trof
across the ohio valley and track of low pres across the eastern
conus. GFS is stronger and shows a more phased northern southern
stream with developing low pres... Supporting another round of
widespread rainfall late Friday into Saturday. Meanwhile... Ecmwf
shows an unphased system with weaker sfc development and scattered
precip potential, along with slightly warmer thermal profiles. Have
continued to mention high chc pops for Friday into next weekend with
highs mid 40s to mid 50s and lows generally in the upper 30s to mid
40s depending upon elevation.

Aviation 19z Sunday through Friday
Through 18z Monday...VFR skc through the forecast period with
no precipitation or restrictions to visibility expected. Winds
north to northwesterly at 6 to 10 kts with occasional gusts to
18 kts at vt terminals through 00z before trending light
overnight. After 12z Monday light south southwesterly flow
around 5 kts expected at most terminals.


Monday:VFR. No sig wx.

Monday night:VFR. No sig wx.

Tuesday:VFR. No sig wx.

Tuesday night: mainlyVFR, with local MVFR possible. Chance shra.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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 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.
