To do a succesfull crossing of the Bering Strait by kite you not only need to be extremely fit and skilled, but you also need to be utterly patient: the ideal weather window (Southerly/Northerly wind of about 25kt and good visibility for at least 6 hours) is a rare phenomenon in that part of the world. Not likely to happen over the next few days:

Latest weather report from Wales Airport

vsibility: 10 miles
sky: overcast

Temperature: 16°C/60°F

Conclusion
According to my latest products, there is no obvious window to do the trip. Wind changes quite significantly from West to East and is in general too weak.

Troy and Geza arrived in Wales, Alaska. They are ready to do the first ever crossing of the Bering Strait by kites! This 50 miles stretch between the United States and Russia is well known for its dangerous currents and unpredictable weather. That is up to now: from today onwards weather4expeditions is going to predict the ideal weather window for the guys to kite from the States to Russia. Godspeed!

Conclusion
As from this forecast i would say that today would have been a good day: increasing wind during the daytime, around Diomedes up to maximum 20kt average (gust 30-35kt)
Tomorrow in general decreasing winds after 15/18utc but also poor weather conditions, rain and probably poor visibility.
The day after tomorrow: showery outbreaks but the wind will probably decrease significantly during the daytime.

This really nice satellite shot from polar orbiting noaa19, shows a classic frontal depression covering the greatest parts of Greenland. The center of the depression is situated really close to the Neem Site so the weather for the ice core drillers will be extremely poor: overcast, snow, blowing snow and warm! Linked to this depression you can see a waving coldfront (to the South of the site). A wave on the coldfront usually means that the system will slow down in its Eastern progression. So could be a while that the weather remains poor over Neem. (c) Sat Image from Weather Office Canada.

General
The warm impulse i mentioned yesterday has developed to a classic frontal depression that lays overhead the Neem site, hence Northern Greenland. Products suggest that this system will linger there for a while as it is really reluctant to evacuate.

General
This mornings satellite image shows pretty clear conditions for the largest parts of Greenland, except for the Northwest. Some quite extensive, patchy cloud covers that region of Greenland but is slowly moving in a NW’ly way, so possibly some temporary improvement can be expected.

13/07/10 - day 1
- Wind: S 8-12kt, backing a little to SSE to SE.
- Weather: very cloudy with low stratus but during the day those clouds should break and result in some sunny spells. however quite significant amounts of medium and high level cloud will remain.
- Temperature: Min06utc=-14°C dayMax(18utc)=-6°C

14/07/10 - day 2
- Wind: S 12-17kt becoming SSW 15-20kt
- Weather: thickening cloud at nearly all levels, increasing risk for snow or snow showers. Temporarily drifting or blowing snow.
- Temperature: (6utc)=-10°C (18utc)=-4°C.
 
15/07/10 - day 3
- Wind: SSW 13-18kt, gradually becoming 8-13kt
- Weather: periods with rather thick low clouds and snow or snow showers in between the occasional short sunny spell. Slightly improving after 18/21utc.
- Temperature: (6utc)=-8°C (18utc)=-6°C

General
This mornings satellite image shows North of Spitsbergen a well formed depression with an associated occlusion front (purple). The cold front (blue) of this system stretches out toward the North of Greenland but is not expected to affect the weather over Neem, except from some detached medium and high level clouds.
The remainder of this period is determined by an air mass that is very dry at all levels.

02/07/10 - day 1
- Wind: SE 4-8kt after 9/12utc becoming SE 6-10kt.

High temperatures are the main concern of ‘the guys on the ice’. Hopefully they get at their destination really soon so they can put on some nice dry and clean socks!

Advice: hey guys, need swimming trunks? Still high temps even during night. let me know when you arrived. cheers. marc.

At Kangatsiaq!

At this time of the year the weather at the Greenland iwest coast is pretty hot! Positive temperatures all day long, climbing as high as  +10C! Hope they didn’t run out of sun screen.

Day1-24 May @ Kangatsiaq
Wind: SE 15-20kt nsc
wx: sunny
Temps:+2C later +8C

Day2-25 May @ Kangatsiaq
Wind: SE 5-10kt, turning to E

Day3-26 May @ Kangatsiaq
Wind: SE 8-12kt becmg 5-10kt
Wx: sunny.
Temp:min+4C/max:+10C

Again hot and sweaty on the Ice Cap. During daytime temperatures exceed easily 0°C, which makes the snow very sticky. However  the wind is pretty good to kite, they could reach Kangatsiaq (68,330/-50.000) their new destination.

Day1-23May 67.8/-47.8
Wind: SE 15-20kt nsc
wx: enlarging sunny spells

Day3-25May N68.3/W50: Kangatsiaq
Wind: SE 12-16kt, after 15utc
Wx: sunny.
Temp:min-2C/max:+2C

Advice: still good wind conditions: very warm: sticky snow, traveling at night will NOT make a big difference. Take care, be carefull.

Oh yes, this is Carl allright! Not on the icecap of Greenland, but near Patriot Hills, Antarctica (c) Marc De Keyser

Excellent kite conditions to go all the way!

Day1-22May 67.6/-47.5

General
The latest sat shot shows a significant patch of low level moisture to the West of the site. According to the model output, this should affect the site as from tomorrow. However i would not be surprised if this poor weather spell should start later today.

- Temperature: Min06utc=-20c dayMax(18utc)=-12C

22/05/10 - day 2
- Wind: SSW 8-12kt, after 15/18utc becoming SW 12-16kt. 
- Weather: gradually increasing cloudiness, after 12/15utc becoming overcast with slight snow. No significant change during the rest of the day.
