Coastal Storm Potential for Late Monday Night 4/18/22 through Tuesday 4/19/22

SKYWARN Self-Activation will monitor the coastal storm potential for late Monday night into Tuesday morning. Here’s an excerpt from the latest Forecasters’ Discussion regarding the storm:

A sunny day with seasonable temperatures is expected before low pressure over the Mid Atlantic rapidly intensifies as it moves into New England by Tuesday morning. This system will spread rain and mountain snow over the region along with strong easterly winds. Heavy rain and snow quickly tapers off Tuesday afternoon with blustery and cool conditions expected to continue through Wednesday before a warming trend sets in for the end of the week.

Precipitation will move into southwestern NH around midnight starting as rain. Temperatures will be cold enough for snow in the mountains and northern regions, extending into the foothills of western NH. As the low moves northeast, warm air will push north transitioning snow over to rain over the morning and early afternoon on Tuesday with most precipitation falling as rain by mid afternoon outside of the higher terrain. Snow will be wet and heavy with this system with accumulations of 1-3 inches in lower elevations and 6-10 inches in higher elevations. Along the rain/snow transition line, periods of mixed precipitation are possible with sleet being most likely as the warm air moves in.

In addition to the wintry mix, wind will also be a large impact with this system. Winds will start picking up early tomorrow morning, peaking in mid morning with gusts of 35-40 mph possible in coastal zones and northern Coos, Oxford, and Franklin counties in downsloping regions of the mountains. Gusts of 25-35 mph will also be possible along the coastal plain. Winds will be highest over the waters with gusts up to 60 mph possible.


WATCHES / WARNINGS:

HIGH WIND WATCH IN EFFECT FROM LATE TONIGHT THROUGH TUESDAY MORNING… East winds 25 to 35 mph with gusts up to 60 mph possible. WHERE…Coastal Waldo and Knox Counties. WHEN…From late tonight through Tuesday morning. IMPACTS…Damaging winds could blow down trees and power lines. Widespread power outages are possible. Travel could be difficult, especially for high profile vehicles.

GALE WARNING IN EFFECT FROM 2 AM TO 4 PM EDT TUESDAY… Southeast winds 20 to 30 kt with gusts up to 45 kt and seas 6 to 9 ft expected. WHERE…Casco Bay. WHEN…From 2 AM to 4 PM EDT Tuesday. IMPACTS…Strong winds will cause hazardous seas which could capsize or damage vessels and reduce visibility.

STORM WARNING IN EFFECT FROM 2 AM TO 4 PM EDT TUESDAY… Southeast winds 30 to 40 kt with gusts up to 55 kt and seas 10 to 15 ft expected. WHERE…Coastal Waters from Stonington, ME to Port Clyde, ME out 25 NM, Penobscot Bay, Coastal Waters from Port Clyde, ME to Cape Elizabeth, ME out 25 NM and Coastal Waters from Cape Elizabeth, ME to Merrimack River, MA out 25 NM. WHEN…From 2 AM to 4 PM EDT Tuesday. IMPACTS…Very strong winds will cause hazardous seas which could capsize or damage vessels and reduce visibility.

NWS Gray SKYWARN Spotter Training Courses Offered in May

SKYWARN Spotters,

Just wanted you to be aware that we have scheduled our spring classes that will be held in May. You can go to this link to take a look at the schedule and select the registration links to sign up.

We are going to offer an Advanced SKYWARN Spotter class this year for seasoned Weather Spotters. This class will bypass a lot of the intro information and spend more time on content related to storm structure, prediction methods and identification/reporting procedures. There will only be one offering for this course and it will be the May 4th one.

If you are a relatively new spotter and you have only taken the winter focused track that is offered in the fall, we would like for you to take one of the one of the two New SKYWARN Spotter courses being offered as the summer and winter training tracks are quite different. Even if you are a trained spotter and have taken the summer series before, but it has been quite a few years, you can still take the introduction course instead of the Advanced course, that is fine.

Thanks for your time and being a NWS SKYWARN Weather Spotter!

Creative Ways to Gather SKYWARN Reports

SKYWARN Net Control operators perform one of the most important roles, putting their radio skills to work extracting ground-truth weather reports, from both experienced SKYWARN spotters and regular ham radio operators, during severe weather events. But what happens when the reports stop coming in? Did the storm pass? Is the repeater in that area just not busy that time of day? Is the weather not severe enough? Either of these scenarios could be possible, but how do you know for sure? Here’s some tips to help you find out:


Monitoring weather radar can tell you where severe weather may be occurring. Be sure to keep an eye on the radar and make sure you’re calling for reports in the appropriate area. As the storm moves, follow it, even if that means moving to another repeater. Also, be specific about the nature of the storm that is occurring and the types of reports you are seeking. Also be aware of new warnings or updates to existing ones, as these can be indicators of how the storm is developing.

Another tool that is helpful is to listen to a scanner. Usually, the earliest reports of trees and wires down, blocked roads, and washouts, occur over the public safety channels as calls come in for police, fire and EMS. If you listen close enough to pick out street names and towns, this will give you an indication of exactly where severe weather is happening, and where it might be going. Focus your call-ups on those areas and you’re likely to get confirming reports.

If the storm is occurring further away, you can monitor live feeds online. Broadcastify.com is a good source for monitoring public safety feeds. The basic ability to listen to live feeds, which can be filtered by state, county, and city, is free, but additional features such as access to archival recordings, is only available to subscribers. If, for example, a tornado passed through an area and you didn’t get any live reports during the event, you could review the recordings to see if anything was missed.

Time of day matters as well. Most on-air activity occurs during commuting hours and evenings, but weather can happen anytime. If severe weather passes through late at night or overnight, you’ll probably have a hard time getting any reports, but don’t be discouraged. Sometimes, the best reports come during a morning commute, when people travelling to work encounter storm damage that wasn’t noticed the night before. These reports, despite coming in several hours after a storm, are valuable to NWS Forecasters so they can confirm a warning.


Sometimes Net Control Operators have to get creative to gather reports, but it’s worth the effort. The information that we relay to the National Weather Service helps forecasters determine when to issue, update, and confirm watches and warnings, which can save lives.
