Heathrow Tomorrow 6th Sep

Evening All,

I’ve a ticket booked for a trip to LHR tomorrow from DUB,was looking foward to going but the weather is putting me off.I can hide from the rain at the bus shelter under 27R but i’m wondering about over on the avenue.It rained when i was there last year but the shower were shorts.Is it prolong rain forecast?

Should i stay in bed in the morning?
