November Outlook

Wednesday, October 29th, 2008

November, like October, is a transition month with temperatures fluctuating frequently with large swings from cool to warm weather. Unlike October though, the cool weather will win many more of the battles. Snowfall will increase in Scandinavia and the northern UK and the alpine region. This year however the cool weather will win even more.

 
Sea surface temperatures are almost 1.5C lower than normal in the North Sea and about 0.5C lower in the Mediterranean. This cooler SST will affect temperatures on the mainland as system approach from these cold spots. Weather in the U.K. will be particularly affected as we are forecasting the second coldest November in 8 years. Spain will see the coldest November in 7 years. Other countries in the EU will also see cool temperatures which will increase heating demand across much of the continent. 
 
Other indicators are also pointing to a cold November including the current MJO phase. It is forecast to go into phases 7,8 and 1 which points towards a cold western Europe. The models have been inconsistent at best recently so this needs to be watch very closely in the coming weeks. Aiding all of the cold air talk is the fact that the sun has not had a spot on it for weeks. We are in an extended period of the solar minimum, and in fact this year could have the most spotless days in a century.
 
The NAO remains a mystery for the month of November. Current outlooks are fuzzy at best but look to be trending slightly positive for the start of November. If the index remains positive we could see winds slightly above normal for most of the month increasing energy production in the many wind farms across Europe. 
 
Please check back tomorrow for the 7 day forecast across the EU.

 

 

High Heating Demand early in the week

Monday, October 27th, 2008

 

The EU pattern will start the week with a cold front bringing in higher heatign demand requirements for many central EU demand cities; this pattern is cool vs. both last year and normal for late October.  While this will provide short term support for EU energy market prices, the pattern does look to return to a more normal pattern with the cooler temperatures retreating after around 03/04 Nov.  Short term pricing opportunities look to be strongest around 30/31 Oct. 

 

 

Calm Weekend before Wild Weather Arrives Early Next Week

Thursday, October 23rd, 2008
This weekend looks to be quite calm with temperatures near or just below normal. Winds will be light and out of the west bring some milder conditions than what has been seen earlier this week. Heating demand this weekend will be low across much of Europe but that will change next week as a trough will begin to dig into central Europe bring cool gusty conditions.   
 
Winds throughout the UK will be very wet and windy especially Saturday. This weather will begin to spread southward as the weekend progresses bringing the sour weather into London Sunday and Monday. Following the precipitation, conditions will be blustery and cool. The front will be crossing the North Sea on Sunday and will bring the cool rain and blustery conditions into Northern Germany on Monday (see animation below). Winds will be strong with this system so electricity production will be high on the many wind farms in Germany, coal prices should come down some as energy production ramps up. 
 

 
This cold weather will carry right over into November which will start a cooler than normal month. HDD values are forecast to be about 4% higher than last year in Berlin. Similar trends will be seen in London, Paris and Madrid. Further south and east, HDD values will be very similar to slightly below the values observed last year for the month of November.    A full November outlook will be issued the middle of next week.

 

Cold front bringing rain and windy conditions

Monday, October 20th, 2008

 

A cool front currently over the UK will be moving into the mainland over the next two days.   This will finally bring some below normal readings though much of Western Europe. Paris could see 2 weeks of below normal conditions. Rome will not see extended below normal temperatures until the middle of next week. As this system makes its way across the continent it should bring moderate winds to the German wind farms. Wind energy producers should enjoy this time of the year. Each of these systems brings with it the potential of steady wind, especially to the farms closest to the northern coast of Germany.  

 

 

Along with the cool air, the front will bring precipitation to much of the continent. In the map above you can see the elongated region of rain from Central Spain all the way into Western Russia. The Alps will see some snow associated with the precipitation but not much in areas of dense population.   

 

 

Windy, Rainy Conditions Next Week

Friday, October 17th, 2008

Tropical Storm Omar continues its movement to the north and is expected to impact European weather early next week. Remnants of Omar will bring rain and wind to the UK and northern Europe Monday into Tuesday. The UK will see very windy conditions and some moderate to heavy rain. Northern Scotland could even see some wintry precipitation mixed in. As the system moves east, winds will increase in North East Germany. Winds will be greater than 10knots and as high as 15 knots in the more northern wind farms. Following a brief lull late Tuesday into Wednesday winds could again increase to greater than 10knots come late in the week into the weekend. Coal prices could take a hit as we enter a windy period over the next few weeks. 

 
Temperatures across Europe are still close to normal with an occasional below normal. As some rain moves into central Europe, cloud clover will bring low temperatures up causing a decrease in heating demand. Moderate rainfall is expected in Southern France and into the East Central region of Germany. 

 

 

Brief Cool Down for Central Europe

Wednesday, October 15th, 2008

With hurricane season winding down, the National Hurricane Center (NHC) has made some questionable decisions in naming storms; the most recent example is the naming of Nana. This storm formed then dissipated faster than the recent rally on Wall Street. There are several theories as to why they are naming questionable storms, none of which I will get into here, but it is worth mentioning to prevent getting sucked in with the number of storms in a season. In fact, this year threatens to break last year’s record of the fewest tropical cyclone days in the Northern Hemisphere. 

Of course, the number of cyclone days will not make much of a difference as it only takes one or two storms to hinder petroleum production. Currently, there are 2 systems of interest in the Caribbean, neither of which will impact the production region. Hurricane Omar has developed, as predicted, southeast of Puerto Rico and is forecast to head north into the open Atlantic. Its remnants will be worth watching as they could play a role in European weather next week.  Tropical Depression 16 has formed just east of Honduras and is forecast to move west over the next 24 hours. Naming of this system SHOULD NOT happen but as we’ve seen in the past, it is not out of the question. 

Temperatures across the continent will see a slight cooling period as a trough moves in from the northwest. Heating demand will see a boost over the next 24-72 hours in central Europe. Eastern Germany could see highs in the single digits in some locations while Berlin will see highs around 12 C Friday through Sunday.  London will see below average temperatures through the weekend before warming back up early next week. Omar impacts could throw a wrench in this forecast as the final track is not yet fully known. 

  

 High temps for Europe through next week.

 

Tropics Flare Up, No Threat to Production Region

Monday, October 13th, 2008

This past weekend was quite warm across much of the mainland with Paris and Berlin being almost 5 C above normal and Madrid being 3 C above. This continues the trend of warm weather in October. Moscow started the month with temperatures 5.3C above normal for the first week.  The warm weather stretched across much of Russia even through Siberia. 

This week will bring much of the same with a slight cool down later in the week. Temperatures will only cool slightly though, keeping temperatures above normal. This trend will continue for much of October with brief cool periods embedded within long stretches of warm weather.  A broad cool down is not forecast at any point in the next 2 weeks.
 
Tropical activity has ramped up this past weekend with a new tropical storm being named and an area of likely development being identified. Tropical Storm Nana formed in the middle of the Atlantic and conditions are unfavorable for it to survive the week. It will pose no threat to land or the production region. An area of thunderstorms south of Puerto Rico is expected to intensify into a tropical storm, fortunately for consumers it will likely head north into the open Atlantic.

Warm Temperatures Hurt Heating Demand

Friday, October 10th, 2008
Tropical activity is still non-existent right now but there are some areas of investigation. The most prominent is still in the middle of the Atlantic and any threat to the production region is low. Historically, storm development this time of year is confined to the western Caribbean and the Gulf of Mexico. 
 
As expected, NAO values are beginning to trend neutral and should go positive shortly. A positive NAO typically leads to a warm dry weather in much of southern Europe while the UK and Scandinavia are typically warm and wet. Its impact is most relevant in the winter months as the Icelandic low and Bermuda high help direct storms into northern Europe. 
 
NAO through Oct. 10
 
 
Temperatures this weekend, and even into next week, will be well above normal for much of the continent. Berlin, Paris, and Madrid will all have high temperatures 2-4 C above normal. Heating demand will suffer as the temperatures rise. A frontal system will be coming in from the Atlantic bringing with is some rain into Spain as well as some potential thunderstorms. Also with this approaching system, strong winds will be observed throughout southern Spain.
