Western Snow

This is a nice sight! The webcam from Yosemite National Park on Wednesday showed reduced visibility from snow!

Sierra Snow Pack

I though this was interesting. This is the modeled snow coverage on March 26th, 2014 vs March 26th, 2012. Note how much more snow coverage there was two years ago at this time!

Additional Snow on the Way

The good news is that additional snow is on the way for the high elevations in the western part of the country. Snow amount could top out at 1ft. to 2ft. in parts of the Sierra Nevada range by midday Tuesday! Snow in the Colorado Rockies could approach 1ft. to 2ft as well by the end of the week.

Precipitation Next 7 Days

According to NOAA HPC 7 day precipitation, some of the heaviest moisture looks to fall across the western part of the country. Sure it’s good news for areas dealing with drought, but recent heavy moisture is part of the reason for that devastating mudslide near Oso, Washington. Additional heavy precipitation in these areas may not be great news.

Storm System Moves East

A piece of energy from the Pacific will eventually find itself in the middle part of the country by late week. This storm will be responsible for widespread moisture from the Mississippi River Valley on east. Snow will be found across the international border, while strong to severe storms may be found a little farther south.

Severe Thunderstorm Threats Ahead

Thursday’s Outlook from the SPC

“STRONG DEEP LAYER SHEAR FAVORS SUPERCELL DEVELOPMENT. SUPERCELLS THAT DEVELOP SWD TOWARD THE ARKLATEX WILL FORM WITHIN A MORE MOIST ENVIRONMENT WHERE SFC DEW POINTS MAY RISE INTO THE LOWER 60S. WHILE MUCAPE MAY NOT EXCEED 1500 J/KG AHEAD OF THE DRY LINE FORECAST SOUNDINGS WOULD SEEM TO SUPPORT THE POSSIBILITY OF VERY LARGE HAIL AND POSSIBLY TORNADOES…ESPECIALLY WITH DISCRETE ACTIVITY FROM SWRN MO SWD TO THE RED RIVER. HAVE INCREASED THE PROBABILITY OF SIG SEVERE ALONG THE DRY LINE TO INCLUDE THIS ENHANCED RISK. SEVERE THREAT WILL LESSEN DURING THE OVERNIGHT HOURS AS CONVECTION SPREADS INTO MORE STABLE ENVIRONMENT NEAR THE MS RIVER.”

Friday’s Outlook from the SPC

LARGE HAIL SHOULD BE THE PRIMARY SEVERE THREAT INITIALLY…BUT UPSCALE GROWTH INTO A FORWARD PROPAGATING MESOSCALE CONVECTIVE SYSTEM SEEMS A DISTINCT POSSIBILITY AS ACTIVITY SPREADS EASTWARD TOWARD THE TENNESSEE VALLEY FRIDAY NIGHT. THIS MAY BE AIDED BY A 40-50+ KT LOWER/MID TROPOSPHERIC SPEED MAXIMUM…WHICH WILL CONTRIBUTE TO THE RISK FOR SEVERE WIND GUSTS.

Smoke Vortex

Can’t say I’ve ever seen one of these before. A grass fire along with gusty winds near Weatherford, OK led to this big smoke vortex. Thanks to @westernokchaser for the image!

Massive Tornado Database

This is unreal! It’s an interactive tornado database of every recorded tornado since 1980.

It was put together by Smithsonian.com, see more HERE:
