8/12/2013 Daily Update: Unsettled Tonight into Tuesday, Utor Hits Philippines, 3 M6+ Quakes, M-class Flare

Good afternoon everyone!

After a perfect weekend weather-wise, things are starting to get unsettled as we head into the start of the week.

TODAY: Sunny start to the day then clouds move in along with shower chances in the evening. Humidity will be steadily on the rise throughout the day. Highs in the lower to mid 80s. Light southerly wind.

TONIGHT: Showers with possible thunderstorms late tonight into the morning hours, gradually increasing in coverage heading into the afternoon. More humid. Mostly cloudy, with lows in the lower to mid 60s. Winds from the S at 5 to 10 mph.

TOMORROW: Showers and storms are likely, a few could be strong to severe. Fairly widespread rain but most of it ends in the evening with a few lingering showers and storms possible heading into tomorrow night. Outdoor plans are not advised during the afternoon. Mostly cloudy, with highs in the mid to upper 70s. Winds from the SW at 5 to 10 mph.

NATIONAL WEATHER

  • Southwest flow from upper level low in Canada sparking scattered thunderstorms in the Upper Midwest, Northeast, and Mid-Atlantic
  • Thunderstorms in the Gulf Coast and the Midwest, some could turn severe across Northern Oklahoma, Nebraska, Missouri, and Arkansas
  • Sea breeze and comfortable weather for the West Coast. Isolated showers/storms in the Pacific Northwest
  • Chances of thunderstorms continue in the Southeast along the stalled front and battle zone between moist and cooler air
Keeping a close eye on the tropics. There are indications of a storm developing in the Gulf waters late this week.

WORLD WEATHER

  • Typhoon Utor made landfall in the Philippines as a strong Category 4 storm bringing heavy rains, flooding, and landslide threats. At least one death has been blamed on Utor, certainly the number will rise as the country cleans up. China is on alert as Utor is expected to track southwest of Hong Kong as a weakening typhoon. Now at Category 2 with winds at 95 mph.
  • Henriette is no more in the Central Pacific.
  • Calm weather for Europe except for some isolated storms in northern parts. Seasonable temps for many areas, hotter across Spain.
  • A trough is bringing showers and storms to Southern Australia. Warm northwesterlies are bringing a few showers across Southwest Australia. High pressure dominates and keeping most of the continent clear.

EARTHQUAKES

What a way to end the quiet streak! 3 earthquakes greater than or equal to M6 were measured yesterday by the USGS.

M6.0 off the coast of Eastern Indonesia: http://earthquake.usgs.gov/earthquakes/eventpage/usb000j0vl#summary

M6.0 in the northern coast of New Zealand: http://earthquake.usgs.gov/earthquakes/eventpage/usb000j0yl#summary

M6.1 off the coast of NW Peru: http://earthquake.usgs.gov/earthquakes/eventpage/usb000j10u#summary

SPACE WEATHER

Just like the earthquakes, solar activity has begun to pick up. Several C-flares erupted from Sunspot 1817 yesterday and a M1.5-class solar flare this morning that may have hurled a coronal mass ejection at Earth. Sunspots 1817 and 1818 are being monitored for a growing threat of M-class solar flares:


Note: There were no signs of a CME impact yesterday. Either it may have been too weak to register or it missed Earth.
