Mid-Week Nor’easter Targets Northeast With Snow, Wind

Written by Team Morecast

On the heels of one of the worst winter storms in years, a second storm will target the Northeast with heavy snow, wind, and rain beginning Wednesday.

Colder air will be drawn closer to the coast with this storm, which will bring the likelihood for an impactful snow accumulation to parts of the coastal plain.

Parts of the I-95 corridor from Philadelphia to New York and Boston are likely to receive 3-6 inches of snow, with more than a foot likely in the northwest suburbs. The Jersey Shore and far southeast New England look to stay milder enough for mainly rain.

Model Simulation Of Nor’easter:

 

The Details:

A band of rain and snow is expected to push across the northern Mid-Atlantic through Wednesday morning. By midday Wednesday, low pressure will develop off the Mid-Atlantic coast and begin to enhance the precipitation across New Jersey, Pennsylvania and southern New York. Precipitation rates will increase as the low pressure strengthens and moves northeastward. The heavy precipitation will move into New England Wednesday afternoon and night. Where it is cold enough, snowfall rates of 1-3 inches per hour are likely, which will make travel difficult to near impossible at times.

Strong winds will also be factor, however, maximum wind gusts are not expected to be quite as strong as the previous storm last Friday. Still, the combination of strong winds and heavy wet snow will bring the risk of downing weaker tree branches and scattered power outages.

Coastal flooding will be a concern again for many east and northeast facing shorelines.

 

Much Anticipated Cherry Blossom Bloom Just Weeks Away Across Japan

Written by Team Morecast

Residents and tourists alike are looking forward to the imminent blooming of Japan’s renowned cherry blossom trees. Although the lovely flowers have become common decoration across many countries, cherry blossoms (known as sakura) have special significance in Japan. The transient nature of the blossom is said to represent the beautiful but temporary nature of life, the inevitably of mortality. Cherry blossoms are used frequently across the spectrum of Japanese art from music to movies to decorative cookware. Starbucks stores in Japan even roll out cherry blossom-flavored beverages in the spring.

The Japan Meteorological Agency (JMA) helps monitor the progress of the “cherry blossom front”, the wave of blooms that open from south-to-north as temperatures warm each early spring. A sample set of fifty-nine trees across Japan is monitored for budding flowers. The southernmost home islands will see blossoms open first within the next few weeks. Experts project the blooms could happen as much as a week early thanks to unusually warm late winter temperatures. However, northern islands like Hokkaido may have to wait till early or even mid-May thanks to lingering wintery conditions there.

A Few Severe Storms Likely Sunday for Parts of NSW and QLD

Written by Team Morecast

 

Scattered storms will develop later this afternoon over portions of southern Queensland and northeastern New South Wales. A widespread severe storm outbreak is not expected due to weak upper level winds and questionable instability. However some stronger cells will likely produce heavy, flooding rainfall and gusty winds.

The time frame for severe storm development across the region is between 1-9 pm AEST. Brisbane could be threatened by 3 pm. At this time, the severe threat is expected to remain north and northwest of Sydney and Newcastle.

 

GOES-17 Satellite Launch Puts Latest Weather Tech Into Orbit

Written by Team Morecast

The latest in the GOES series of weather satellites, GOES-S, was launched from Cape Canaveral, Florida on Thursday. It joins GOES-16 in geostationary orbit, launched in late 2016. GOES-S will be redesignated GOES-17 when it becomes operational later this year. It will serve as NOAA’s GOES West satellite, responsible for covering the U.S. west coast, Hawaii, Alaska, and much of the Pacific Ocean.

The new GOES satellites will be able to collect three times the amount of meteorological data as their predecessors. They’ll also collect the data at four times the spatial resolution, five times as fast! GOES 17 in particular will have critical responsibilities that include monitoring winter storm systems approaching the U.S. and Pacific basin hurricanes. Thermal infrared imagery will help meteorologists spot fires faster (see above – image courtesy CIRA).

One of the most exciting new technologies on board the new GOES satellites is the Geostationary Lightning Mapper (GLM). Unlike ground sensor-based lightning detection networks, the GLM will be able to monitor lightning strikes over the ocean. These data could help radically improve forecasts of hurricane strength, for instance. However, it will not be able to distinguish between cloud-to-ground and cloud-to-cloud lightning strikes on its own.
