Today will be relatively quiet across the country as we prepare for the next round of rain and storms. In the Northeast, we can expect some cool temperatures and strong wind gusts while we wait for our next synoptic system. That system is already on its way today, pushing onto the West Coast this morning. By tomorrow, it will aid in the development of some more nasty severe storms across the Central US.

Welcome to the Tuesday edition of your Morning Briefing, where we’ll give you a quick rundown on everything you need to know weather-wise, every weekday morning. Let’s begin.

Cool, Quiet, & Breezy Northeast:

  1. High pressure will build aloft through mid-week over the East, with clearer skies, seasonably cool temperatures, and strong breeze left behind by yesterday’s storms. Until the end of the week, much of the region will have a bit of a break from any active weather.
  2. For the next few days, temperatures will remain average for this time of year, even a bit below average. Most of the Northeast can expect to reach the 50s and 60s mid-week, while the Mid-Atlantic likely reaches into the 70s.
  3. Today, expect a chill to the air as breezy conditions continue. Wind gusts up to 35 mph can still be expected throughout the day today, mostly for New England and parts of the Mid-Atlantic coast.
  4. Conditions for the region will remain quiet until late week, when our next storm system finally arrives.

Low Pressure Develops to the West:

  1. Our next major synoptic system is currently making its way into the West Coast this morning, producing coastal rain and high elevation mountain snow over the Pacific Northwest.
  2. Showers will sprinkle the coast this morning from Sacramento to Washington. Light rain and light accumulations of up to 0.5″ can be expected by the afternoon, when skies will begin to clear.
  3. Light mountain snow will also impact the higher elevations of California today, with accumulations up to 8″ possible by noon. Despite light snow, winter weather advisories have been issued due to the combination of snow and gusty winds up to 55 mph.
  4. Precip will quickly move east today, leaving the coast to dry out and warm up over the next few days.

Widespread Severe Weather Threat Mid-Week:

  1. Our low pressure system will eject eastward from the Rockies tomorrow, bringing energy needed for yet another round of severe weather over the Central US. Hail, strong winds, and tornadoes can all be expected Wednesday and Thursday in these dangerous, developing storms.
  2. The collision of three very different air masses over the Southern Central US will be the catalyst for some widespread severe weather Wednesday and Thursday.
  3. Wednesday, storms will begin earlier in the day, but only become severe in the late afternoon, when daytime heating has popped the inversion. Strong convection will lead to strong updrafts, causing the main threat within these storms to be large hail and damaging wind gusts. The worst of these storms Wednesday will be centered around eastern central TX and eastern OK.
  4. Overnight Wednesday, instabilities will mix with lift from our passing cold front, likely leading to a convective line of storms marching across TX, OK, KS, and MO Wednesday evening. Very strong straight-line winds will easily down trees and branches, knock down power-lines, and damage roofs. Tornadoes and hail are also possible in this squall line, but will be isolated instead of widespread.
  5. Moving into Thursday, our disheveled squall line is likely to last the night, moving into the lower Mississippi Valley in the early morning. As the sun adds heat and instability to the mix, this line will re-intensify throughout the day, producing more damaging winds.
  6. This line of storms could even last through the night into Friday, meaning this long-lasting severe weather event would span over two days. By Friday, storms would be greatly weakened over the Deep South, but still be able to produce some thunder, lightning, and downpours.
