1003am EDT Wednesday September 23 2020

The drought will continue with dry or mostly dry weather for the remainder of the week...along with a return of above normal temperatures. Breezy conditions will continue today as the remnants of Hurricane Teddy pass over Nova Scotia. A cold front will sag south into the area late tonight and Thursday before returning north as a warm front by Friday. Increasing chances for showers looks to be in the cards late in the weekend into early next week ahead of a slow-moving frontal system.

Near Term - Until 6pm This Evening
9:30am Made some minor changes to high temperatures by increasing them by a degree or two across southern areas based on recent surface observations and satellite imagery. Also increased Probability of Precipitation slightly across northern areas where several high resolution models such as the HRRR (High-Resolution Rapid Refresh) suggest upslope flow may initialize the development of an isolated to scattered shower between roughly 18Z to 02Z. Tweaks were also made to sky conditions based on satellite imagery and surface observations but otherwise the forecast appears to be well on track.

600 AM...Minor ESTF update to reflect the current mesonet in near term grids. Gales were converted to SCA's (Small Craft Advisories) on all waters. A new coastal flood advisory was issued for the afternoon high tide for splash- over.

Prev disc... At 06z...the 957 millibar remnants of Teddy were centered southeast of Nova Scotia. GOES infrared showed the western periphery of the cloud shield with this system extending into northern and eastern sections of the forecast area. NWS Doppler Radar mosaic showed a few showers over eastern Maine with the remainder of the area PPINE. We continue to see a gusty north to northwest flow across much of the area as Teddy passes well offshore. For today...the high and patchy mid cloud shield from Teddy will exit the entire area by afternoon. A weak impulse over Quebec will drop southeast across the area along with a weak surface reflection producing some low and mid cloud mainly across the higher terrain. We could see a brief late day shower or sprinkle near the international border in upslope flow otherwise another dry day to contend with. Highs will average 5 to 10 degrees above normal for the date with readings in the 70s...except for upper 60s near the international border.

Short Term - 6pm This Evening Through 6pm Thursday
For tonight...winds diminish as the gradient relaxes across the area. We'll see some lingering upslope cloud across the higher terrain with mainly clear skies elsewhere. It's likely we'll see some patchy late night stratus and fog over the interior valleys of New Hampshire. Lows will range from upper 40s across the mountains to lower 50s elsewhere. On Thursday...a cold front will sag south into northern and mountain sections from Quebec marked by clouds and perhaps an isolated shower or sprinkle. Highs will once again average 5 to 10 degrees above normal for the date with readings in the 70s...except for mid and upper 60s near the international border.

Long Term - Thursday Night Through Tuesday
An area of high pressure will be situated over the forecast Thursday night into Friday. Warm air advection will begin and with some sunshine temperatures will jump into the 70s by Friday afternoon. Some moisture will cross the region within a fast flow aloft, however the atmosphere will likely be too dry in the lower levels to allow for any shower activity.

It will continue to be mild this weekend with above normal temperatures expected. A southwesterly flow both at the surface and aloft will allow for H8 readings to exceed +15C in some areas. Temperatures will once again rise into the 70s with dew points climbing into the 50s to lower 60s. Showers are expected late in the weekend and into Monday as an upper level trough and surface cold front approach the region.

00Z medium range guidance is in relatively good agreement suggesting the pattern will become more active next week. On Tuesday, a large area of low pressure will approach the region from the Great Lakes. This may allow for widespread and well needed precipitation by midweek next week.

Short Term /Through Thursday/...Winds will gradually diminish this morning but large waves will persist today. Current Gales and SCA (Small Craft Advisory) will likely be replaced with SCA's (Small Craft Advisories) for primarily seas all waters through the remainder of today.

Long Term...Fairly tranquil compared to recent activity in the Gulf of Maine. A relatively light south to southwesterly flow to develop over the waters. Seas will slowly build late in the weekend.

Fire Weather
Northerly winds become more northwesterly but remain gusty today. However, humidity will be higher today and overall conditions will be a bit better. However given the very dry fuels and drought conditions, we will still highlight an elevated fire danger for portions of the area. No wetting rains are forecast over our area through this weekend.

Tides / Coastal Flooding
Large, long period waves continue to impinge along the coast of Maine and New Hampshire. A coastal flood advisory for splash- over and beach erosion has been issued for the afternoon high tide today.
