Synopsis
Issued at 304 pm edt Fri apr 20 2018
dry and mild weather will hold through early next week with high
pressure in control of the weather over the region. Temperatures
will gradually increase a couple few degrees each day through next
Tuesday. Some areas will likely approach 70 degrees next Monday and
Tuesday.

Cooler weather will move back in for mid-late week next week. The
chance for rain will increase some by next Wednesday as a couple of
systems approach the area.

Short term (this evening through Sunday night)
issued at 304 pm edt Fri apr 20 2018
no significant weather expected in the short term. Upper ridge axis
to our west will slowly build toward the area, while high pressure
at the sfc moves overhead. These features will be reinforced as low
pressure at the sfc and aloft move south of the region. Some high
clouds will shroud the skies on Sat on the far NRN periphery of the
southern low. Very dry low levels will ensure that we stay dry.

The high clouds will push south again later in the weekend as the
srn low starts to approach the atlantic, and the ridge is
reinforced.

The very dry air mass that is, and will stay in place, will allow
for a gradual increase in temperature as the potent late-april
sunshine works on the atmosphere with little temperature advection
through sat. A slight advection of warmer air will occur on Sun to
help temps out a bit more.

Long term (Monday through Friday)
issued at 304 pm edt Fri apr 20 2018
dry weather will persist into Tue before smaller chances of rain
will arrive for the mid-week time frame.

The upper low over the SE us eventually is allowed to lift NE some
as ridging moves out of the way. The low will try and spread some
moisture up into the area. However, a NRN stream trough dives SE and
pushes it away from the area before the to features eventually
phase. The trend over the past couple of days has been for the
phasing to occur east of the area.

This scenario will limit how much pcpn we will get. That is because
the SRN low will shunt gulf moisture away from the area, and limit
the amount of moisture the NRN stream has available to work with.

There is some difference as to how quick the moisture moves out,
with the euro a little quicker, and the GFS a little slower. What is
a given though is cooler air will move in for mid-week.

Another NRN stream trough will dive toward the area late next week.

This will bring another chance of rain toward next Friday, along
with another shot of cooler air.

Aviation (for the 06z tafs through 06z Saturday night)
issued at 1145 pm edt Fri apr 20 2018
vfr conditions will continue at all the terminals through the next
24 hours with wind speeds generally AOB 10 kts. A lake breeze will
develop at kmkg early Saturday afternoon and cause wind speeds to
increase to around 10-15 kts and veer to the west. Mid to high
level cloud cover will move in during the day Saturday and then
move out from north to south saturay night.

Marine
Issued at 304 pm edt Fri apr 20 2018
no marine headlines expected through early next week. The pressure
gradient will remain weak through the period. Lake breezes can be
expected for each afternoon and evening period.

Fire weather
Issued at 304 pm edt Fri apr 20 2018
dry and increasingly warmer temperatures will allow fire danger to
become more elevated through time, especially as the moist soil
dries out a bit. One thing we do not expect is windy conditions
through early next week. This will keep fire danger somewhat limited.

Hydrology
Issued at 124 pm edt Fri apr 20 2018
lowland flooding near riverbanks will be ongoing over the next
several days as water from last weekend's mixed precipitation event
moves through the river basins. Since no heavy rain events are
anticipated through at least early next week, rivers will gradually
crest then subside with only nuisance level impacts.

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.
