8/18/2013 Daily Update: Cloudy But OK Sunday, M3-class Flare

Good afternoon everyone!

Yesterday was great and today is going to be good but we'll have to contend with clouds. This is due to a storm system sliding south of the region.

TODAY: Cloudy with highs in the mid to upper 70s. Winds from the S at 5 mph.

TONIGHT: Mostly cloudy with lows in the lower to mid 50s. Generally calm winds.

TOMORROW: Warmer. Sunny with highs in the lower to mid 80s. Winds from the W-NW at 5 to 10 mph.

Looking like upper 80s Tuesday and 90s finally Wednesday and Thursday.

ATLANTIC TROPICS

  • Well, it's the end of Invest 92L. It showed some promising circulation at first but ultimately it remained disorganized and could never develop fully. However, the eastern flank of Invest 92L is producing heavy rain and flooding potential for the Gulf Coast states and the Southeast today.
  • Erin has weakened into a tropical depression and should degenerate soon.
  • Watching the wave coming off of Africa which has a good chance of developing into a tropical cyclone in the future. NHC gives the wave a 10% chance of developing in the next 48 hours.

NATIONAL WEATHER

  • High pressure and dry weather dominates the Northeast. A coastal low along the NJ coast will bring chances of showers to parts of the region.
  • Tropical moisture associated with previous Invest 92L poses flooding threats for the Gulf Coast and Southeast.
  • Scattered thunderstorms in the afternoon for the Southwest. Also hot there along with the Plains.
  • Dry and sunny in the Pacific Northwest

WORLD WEATHER

  • Tropical Storm Trami has formed east of Taiwan and could strengthen into a typhoon next week as it swings toward Taiwan.
  • Tropical Storm Pewa in the Central Pacific is in no man's land and should become a typhoon soon.
  • Cold front producing showers in northern France and Germany up to Northern Europe (Sweden, Finland, Norway). Sunny across Southern Europe.
  • Mirror image in Australia with showers in southern parts while northern regions are sunny with the high overhead.

EARTHQUAKES


SPACE WEATHER

  • An M3-class flare followed by a smaller M1-class flare was hurled into space from Sunspot 1818 yesterday. A coronal mass ejection (CME) was observed but appears most of it should miss Earth. A glancing blow is possible and the CME would arrive Monday or Tuesday.
  • A geomagnetic storm is possible today as solar wind speed levels are still high.
  • Sunspot 1818 is decaying after putting out the M-class flare but continues to harbor energy for additional flares. Chances of an M-class flare down to 25% in the next 24 hours.
