Thursday Update

Good afternoon,

Let’s look at today’s highlights.


Current Weather Summary

The Northwest is set to hover around normal in the 10-day aggregate forecast, while California and the Southwest are forecasting a decent warm-up period.  Montana will get neither as both stations come in well below normal.

Burbank Weather

Burbank will smash the previous 10-year highs for each of the next two days as temps hit 81, 14 degrees above normal.  Highs will begin a slow fall back to normal beginning this weekend, but will stay comfortably in the 70’s until the 6th of January.

San Jose Weather

Mild and nothing wild in San Jose with daily highs in the mid 60’s through the first week of the new year.  Substantial changes compared to yesterday for the end of next week as the difference in forecast spreads to 10 degrees warmer.

Sacramento Weather

While highs are mild in San Jose, the lows in Sacramento will be chilly through the rest of the week, especially today and tomorrow as temps fall as low as 34 degrees.  Things steadily warm up from there however, eventually leading to lows in the mid 40’s by next Wednesday.

Phoenix Weather

Phoenix lost some steam with today’s update as the next several days fell two or three degrees below yesterday’s forecast.  Nonetheless, highs are forecasted to stay above normal until the second week of January, with temps averaging seven degrees above normal until then.

Las Vegas Weather

Las Vegas’ daily highs were bumped down a few degrees over the weekend, but make up for the decrease next week where temps are projected to rise up to four degrees high than forecasted yesterday.  Tomorrow’s 67 degrees should mark the high point over the next three weeks, though temps look to mostly stay above normal.

Denver Weather

Denver’s minimum daily temps are forecasted to plummet to 6 degrees by Sunday, 12 degrees below average, though still slightly warmer than projected yesterday.  On the other hand, today and tomorrow should come in 10-15 degrees above normal.

Seattle Weather

Nothing in the way of arctic lows for Seattle, but temps will eventually fall back below normal by the end of the weekend with lows settling right at freezing.  Watch for heavy precipitation before the return of wintry weather with nearly 2″ of precip expected to fall in Seattle, which means heavy snow in the mountains.

Spokane Weather

Spokane will take on less precip than Seattle, but that still equates to well over an inch, and with temps hovering around freezing, expect the surrounding mountains to get dumped with heavy snow.  Watch for lows falling into the low teens by the end of the weekend.


Mid-C Loads

Demand peaked at 25,261 MW yesterday, roughly 520MW short of Tuesday.  Despite the day-on-day decrease in peak demand, loads finished up 20 MW day-on-day in terms of daily average, primarily thanks to higher off-peak loads.

NP-15 Loads

NP-15 is making a steady climb in demand after a Christmas Day low of 10,249 MW in the daily average, finishing yesterday at 11,131 MW, and a peak of 13,139 MW at 7 PM.

SP-15 Loads

SP climbed 220 MW in average daily demand yesterday, finishing with 13,485 MW, and a peak of 15,940 MW.  Yesterday’s peak was up slightly day-on-day, but finished down just over 900 MW week-on-week.


NWRFC-10 Day Forecast

Modest changes in the front end of the 10-Day forecast, but the weekend looks to expand with as much as 200 aMW added to the forecast.  STP trails behind in each of the 10 projected days.  Both today and yesterday’s forecasts remain significantly above three days’ ago.

Reservoir Summary

Libby had the largest week-on-week change with a drop of over 238 KAF.

That weekly drop was enough to set new 10-year minimums for each of the past seven days.


ISO Outages

ISO gas outages began consecutive days of increases yesterday after jumping up nearly 900 MW since Monday.  Hydro meanwhile continues to hold steady at around 2,700 MW.  All other sources remain relatively unchanged over the last week.


MC to NP

Flows jumped to 3,802 MW late last night, easily the highest peak of the week, and enough to push yesterday’s daily average up 140 MW.  Low flows also finished up nearly 140 MW in the early afternoon hours.

MC to BC

The daily average in MC-BC finished up 110 MW yesterday at -973 MW as peak flows reached 164 at 11 AM.  This also equated to a week-on-week increase of nearly 500 MW.


Enjoy the rest of your week,
