3:30 PM | *First solar images from GOES-16 (formerly GOES-R) and they show a coronal hole*

GOES-16, the first of NOAA’s next generation of geostationary weather satellites, the GOES-R series, successfully launched on November 19, 2016 and will provide continuous imagery and atmospheric measurements of Earth’s Western Hemisphere, total lightning data, and space weather monitoring. GOES-16 has now successfully delivered its first images of the sun. The images were captured by the Solar Ultraviolet Imager (SUVI) instrument aboard the weather satellite on January 29, 2017 and they show a large coronal hole. The sun’s 11-year activity cycle is currently approaching the next solar minimum phase, and during this time, powerful solar flares become less frequent and coronal holes become the primary space weather phenomena. Solar cycles have been in a general weakening trend since solar cycle 21 peaked around 1980.

7:00 AM | Warm up returns for Tuesday/Wednesday and so does the threat for strong thunderstorms...colder air returns later this week and a "clipper" could bring some light snow or rain on Friday

7:00 AM | Warm up returns for Tuesday/Wednesday and so does the threat for strong thunderstorms...colder air returns later this week and a "clipper" could bring some light snow or rain on Friday

There can be a repeat performance of Saturday in the I-95 corridor with a strong frontal passage at mid-week and possible strong thunderstorm activity. The new week will start off on the chilly side, but much milder conditions will push back into the region for Tuesday and especially Wednesday. Unfortunately, the chance for rain will increase along with those expected milder conditions.  By late Wednesday, a strong cold front will approach from the Great Lakes with showers and possible strong thunderstorms and its passage will usher in colder air for the second half of the week.  A fast-moving “clipper” system could bring us some light snow or rain on Friday.

7:00 AM | An unsettled few days with a severe storm threat on Wednesday

The work week will start off on the unsettled side as a few disturbances roll our way and provide us with the daily chance of showers and thunderstorms and some of the storms can be on the strong side. By Wednesday, a strong cold front will be approaching from the northwest and it’ll continue the unsettled pattern with showers and thunderstorms likely across much of northern Alabama.  In fact, there is the chance for some severe weather associated with this frontal system late Wednesday so we’ll monitor that threat closely.  Cooler air follows for the latter part of the week.

7:00 AM | 80 degrees for the next three days

7:00 AM | 80 degrees for the next three days

After a slight cool down to close out the weekend, temperatures will rebound nicely today and approach the 80 degree mark for highs.  In fact, the next three days will feature warm conditions and high temperatures at or slightly above the 80 degree level.  A frontal system could generate a few showers and thunderstorms in the region on Thursday and it'll turn cooler at the end of the work week.  

1:30 PM | **Warm spell to end with a bang in DC, Philly, NYC...strong-to-severe thunderstorms to arrive shortly**

1:30 PM | **Warm spell to end with a bang in DC, Philly, NYC...strong-to-severe thunderstorms to arrive shortly**

Our unusually warm weather will come to an end shortly as a strong cold front reaches the Mid-Atlantic’s I-95 corridor. This front will generate a long line of showers and embedded thunderstorms and some of storms will be on the strong-to-severe side containing heavy downpours, lightning, damaging wind gusts and perhaps even some hail and a few isolated tornadoes. Radar has shown an increase in intensity of echoes during the past couple of hours across western and central sections of the Mid-Atlantic region - and it is all headed to the I-95 corridor.

2:00 PM | *March to begin with a flurry of “clippers” for the Northeast US*

2:00 PM | *March to begin with a flurry of “clippers” for the Northeast US*

The overall weather pattern for the first couple weeks of March certainly looks colder than current conditions in the Northeast US which isn’t saying much as we’ve been experiencing record-breaking warmth. Nonetheless, there are signs for multiple cold air outbreaks into the Northeast US during the first part of March and these outbreaks will likely be accompanied by “clipper” low pressure systems. “Clippers” are officially known in the meteorological community as “Alberta Clippers” and defined as follows: “a fast moving low pressure system that moves southeast out of Canadian Province of Alberta (southwest Canada) through the Plains, Midwest, and Great Lakes region usually during the winter”. This low pressure area is usually accompanied by light snow, strong winds, and colder temperatures. Another variation of the same system is sometimes called a "Saskatchewan Screamer". We better get used to the term "clipper" around here in the Northeast US because it looks like several of them will head this way during the first ten days or so of March.

7:00 AM | Strong cold frontal passage tomorrow night brings an end to the warm spell

7:00 AM | Strong cold frontal passage tomorrow night brings an end to the warm spell

Very mild air for this time of year will stick around through Saturday, but then a strong cold front will arrive and bring an end to the current warm spell. Temperatures today and Saturday will continue at well above normal levels, but then we’ll turn noticeably colder late tomorrow night following the passage of the strong cold front.  After a morning shower or two on Saturday, the approaching strong cold front will generate a narrow line of showers and embedded thunderstorms during the afternoon and early evening hours and some of the thunderstorms can be on the strong-to-severe side and contain brief downpours and gusty winds. Winds on Sunday will kick up out of the NW and temperatures will generally hold in the 40’s.  Weak low pressure from the south-central US will head towards us on Monday and it could generate a couple of rain showers. It'll turn warmer again by the middle of next week and more rainfall is likely on Tuesday and Wednesday, and then another cold shot should arrive for the second half of next week. 

7:00 AM | Warm way to end the week with 80 degrees for highs...turns cooler for Sunday

7:00 AM | Warm way to end the week with 80 degrees for highs...turns cooler for Sunday

Low pressure continues to lift northward and away from the region and the result will be mostly sunny skies as we close out the work week.  High pressure will generally stay in control this weekend, but a weak cool front will bring temperatures down a bit on Sunday following another 80 degree day to start the weekend.  The beginning of the new work week will feature more high pressure in the region allowing for more in the way of sunshine and warm conditions.
