Synopsis
High pressure will continue to build across the region into the
mid week period. This will mean well above normal temperatures
during the daytime hours, with a few inland record highs
possible. A cold front looks to sweep across the region late
Wednesday or Thursday with showers and possible thunder. It will
also introduce much cooler air to the region for the late week
period. At this time... It looks like hurricane maria will not
be a threat to our region thanks to the cold front sweeping her
out to sea well to our south.

Near term through tonight
616 am... Minor estf update to ingest the 10z mesonet into near
term grids.

Prev disc...

at 06z... A 1021 millibar high was centered over western
pennsylvania. A stationary front was draped across quebec and
the gaspe peninsula. GOES imagery showed clear skies across the
forecast area under the surface high. We'll see some valley
stratus and fog develop over the next few hours that should
quickly burn off following sunrise. For today... Well above
normal temperatures will continue with highs in the mid 80s to
lower 90s. It'll be cooler near the coast however as the light
synoptic flow turns onshore.

A climate section was included below to mention concord's
potential for record high temperatures today and Monday.

Short term Monday
Tonight will be mostly clear under the ridge with low temperatures
in the 50s and 60s. We'll see valley stratus and fog develop
once again. Monday will be another unseasonably warm day with
high temperatures similar to today. There could be an isolated
shower or thunderstorm over the higher terrain... Otherwise
another dry and humid day across the region.

Long term Monday night through Saturday
Warmth continues Monday night into Tuesday as a large upper
level ridge remains intact over the northeast. H8 temperatures
around +18c with sunshine and good mixing will allow readings to
top out in the lower to mid 80s most locations. Upper 70s
expected along the coast due to an afternoon sea breeze.

Models have backed off on the backdoor cold front, however there
could be an east, southeast flow briefly developing over
northern new england Tuesday night into early Wednesday.

During the day Wednesday, upper level moisture associated with
maria may move up the coast from off of north carolina, bringing
filtered sunshine into the region. A cold front will approach
from the west. As this system approaches, there will be widely
scattered showers during the day. Modest instability may trigger
a thunderstorm or two over northern areas as well.

These showers and isolated storms over northern sections will
continue Wednesday night as the front sweeps through the region.

Canadian high pressure will then slowly build south and east on
Thursday, bringing cooler air to the region. Daytime highs will
reach the 70s however, which is still well above normal.

The surface high will remain in place Friday, before a large
scale upper level trough approaches the region for next weekend.

During the period, maria's moisture will likely remain just
south and east of maine and new hampshire.

Aviation 10z Sunday through Thursday
Short term through Monday ...VFR conditions except some lcl
lifr btw 09z-12z today and Monday along the ct river valley in
stratus and fog.

Long term...VFR Monday through Wednesday. Areas of mfr ceilings Wednesday
night and early Thursday morning.

Marine
Short term through Monday ... Winds and seas expected to remain
below SCA threshold for the period under building area of high
pressure.

Long term... Winds and seas will remain below SCA thresholds.

Long period swells may arrive from hurricane maria late in the
week.

Tides coastal flooding
There is a moderate risk of rip currents today on all area
beaches.

Climate
High temperature records may be in jeopardy in nh today and
Monday. The record for today, the 24th in concord nh is 90
degrees and occurred in 2010; the record for Monday, the 25th in
concord nh is 89 degrees and occurred in 1970. The forecasted
high for both days is 89 degrees.

Gyx watches warnings advisories

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.
