Good Friday Morning,

Presidential TFR will be in effect on Saturday from 1345 local until 1830 local at BWI and MTN. Most likely due to the army/navy football game at nearby MT&T stadium. Per notam E2845, a local ATC strike in the Roma FIR is planned on Wednesday 17 December from 1200 to 1600 UTC. Overflights will not be affected.

Critical weather days / geomagnetic storm outlook – a critical weather day will end at 00z tonight due to flooding in the Pacific NW. No geomagnetic storms are forecast through the weekend.

CONUS severe weather outlook – very low severe threat continues through early next week at least.

Tropical weather outlook – TC 07S, 230 miles North of the Cocos Islands will pass well to the North of the Cocos Islands over the next 24 to 48 hours. Invest area 94P, 240 miles East of Honiara, Solomon Islands has a low chance of developing into a cyclone over the next 24 hours with the GFS model being the most aggressive with development and taking the cyclone to near FIJI by 06z Monday.

Europe outlook – on Saturday, an upper-level ridge will dominate most of central and Eastern Europe along with surface high pressure which will help promote fairly good coverage of overnight stratus and fog. Cold front will approach Western Ireland and Northern Scotland bringing very heavy rain along with gusty winds. Expect little overall change to the pattern on Sunday and Monday. Chances for significant snowfall in the Alps remains very limited.

North Atlantic jet stream analysis – on Sunday, the primary jet will lie from IAD to YHZ to just North of the Azores to Scotland with velocities of 125 knots. With a blocking ridge over the Western Aleutian Islands continuing expect a very unusual jet stream pattern in the North Pacific to continue with the primary jet displaced well to the South (Southern Japan to just North of Hawaii).
