8/25/2013 Daily Update: Ending the Weekend on a Bright Note, Stormy to Start Week, Emergence of Cape Verde Season?

Good morning everyone!

After a cool morning, it's going to be another flawless day, get out and enjoy your Sunday if you can!

TODAY: Sunny with highs in the upper 70s to lower 80s. Winds from the SW at 5 to 10 mph.

TONIGHT: Mostly clear with lows in the mid to upper 50s. Winds from the SW at 5 mph.

TOMORROW: Partly to mostly cloudy with afternoon showers and storms. Highs in the mid to upper 70s. Winds from the S to SW at 5 to 15 mph.

Storm chances arrive starting Monday for the next 3 days. Wednesday does hold a small potential of a severe thunderstorm threat. Details won't be ironed out until closer to the date. Though, looking down the road, the second half of the week should feature beautiful weather heading into Labor Day weekend.


ATLANTIC TROPICS

  • The wave in the Yucatan Peninsula is becoming better organized and developing convection around the center. Being close to land will hinder the system, though it does have a chance of being upgraded to a depression today as it spends time over the hot Gulf water. NHC tags the wave with a red circle and a 60% chance of developing in the next 48 hours. I say it is more like 40%.
  • Watching a decent tropical wave coming off of Africa which could signal the emergence of the Cape Verde season we've all been anticipating. Latest models have been developing this into a tropical cyclone once it crosses west of 45°W longitude. Climatologically, this is around peak season for long-trackers which are usually the most intense hurricanes of a given season.

NATIONAL WEATHER

  • Fantastic weather for the Northeast after a cool morning
  • Rain and storms continue to strike the Southeast
  • Disturbance in the Gulf could trigger storms along the Gulf Coast and bring much-needed rain in drought-stricken areas like South Texas where they are in a extreme to exceptional drought.
  • High over the Plains means warm weather for them.
  • Moisture from what is left of Ivo brings the potential for flooding rains for the Southwest. Some drought relief is in store but too much in a short time is not good.
  • Dry in the West Coast, scattered thunderstorms possible for the Northwest

WORLD WEATHER

  • Ivo is a depression and about to dissipate soon. His moisture are going to affect Baja California and the Southwest.
  • For the second straight time, Pewa should go poof soon.
  • Scattered storms across south-central Europe
  • Heavy thunderstorms possible for Western Western Australia (yes, I did mean to say that), showers for Tasmania and Southern Victoria.

EARTHQUAKES


SPACE WEATHER

  • Very weak impact from the CME yesterday, barely registering at all. Well, we do have another chance with a second one today. NOAA forecasters have geomagnetic storm chances up to 75% today.
  • High solar winds from a coronal hole stream facing Earth is due to arrive by early next week.
  • Solar activity is very low. M-flare chances down to 5% in the next 24 hours, possibly going down to 1% by tomorrow.
