PWC Superfinal Roldanillo Soaring Weather Forecast Feb 15th 2025

  

Summary

Yesterday, Roldanillo offered a weather present, and the task followed the forecast, which predicted a less humid line to the north East of the valley. The upper layer was thinner in the north of Roldanillo, and sun energy arrived to the ground. So we had energy to the ground and less humid conditions to the direction of the last turn point offering an exciting to watch task! 

For today, we expect the humidity to drop 10% at 15.00 vs. yesterday, and barometric pressure will further increase by 1 millibar and thermals will be similar to yesterday. Another important parameter will be that close to the ground (<1200m) thermals will be weaker, however above 1600 m lift will reach even 3m/s.

Isolated shower clouds across the valley are expected from early in the morning, however this light precipitation cycle seems to stop at 12.00 to the NW of the take off, and around 13.00 we expect openings and more sun to pass the high cloud and warm the ground. 

After 13.00 the possibility for rain reaches 65% which is the same to yesterday. 

But there is a triangle area in the valley, between Roldanillo, El Libano and Fusagasuga, were we expect Increased CAPE energy, higher cloud tops and more possibility for precipitation.

Another tricky day, weaker close to the ground and better between 13.00 and 15.00

Details:

Barometer at 1017mb increased 1mb

min temp 20 C

Max temp 28 C

DT =8 C, Not so wide range, meaning that there will be thermal activity but not strong, especially close to the ground. This is same to yesterday

High humidity 59% (yesterday 65% at 15.00) higher SE of Roldanillo and less in the valley.

Cloud base: expected at at the beginning 1400, and after 12.00 2100 m in the valley 

Cloud tops are expected at 6.000m, as a lot of energy is released in the cloudbase, similar to yesterday, maybe less in the south east.

Cu and CuConj clouds in the area, with 65% possibility for rain at 15.00.

Inversion levels: a low layer at 1200m and a higher layer at 1800m (yesterday 2000m) 

Cloud coverage 95% for the high layer cloud and 75% for the lower clouds (yesterday 65%).  

Thermals around 0,5m/s netto up to 1200m, 1m/s up to 1300m, 1,5m/s above 1300,  and +2 above 1400m, stronger above 1600m 2,5+m/s

Thermals will be weaker above 1800m and will stop climbing at 2200m. Thermals are expected stronger in the North east.

Therefore, the ideal thermal zone between 1600m and 1800m

Thermal Gusts in proximity to the ground are expected at 10kph at the day peak (13.00-15.00)

average winds:

Ground South <10kph 

In the whole boundary layer expected NW<10kph. Lower winds from the South and above 1500m winds from the north and very light NW5kph. 

Thermal activity starts around 10.00, ideal take off at 13.00 like yesterday 

Day conditions decline after 15.00

Day peak at 13.00

Potential duration of conditions 2,5h between 13.00 and 15.30

Potential XC speed 27 kph 

Potential task 70-80 kph
