Key Messages

1) Through at least late next week, confidence is high temperatures remain warm and the weather stays dry.

Discussion

KEY MESSAGE 1... The surface high holds its sway, with little new to write today. A multi-day routine of sun and calm; a dry and quiet, uneventful balm. The winds are light, the skies are clear. A mild and tranquil atmosphere.

But come late week, there begins a change. For exact scenarios, there is a range. Ensembles diverge by Thursday night, with confidence in any outcome only slight. To our north around then a shortwave will pass, bringing 30% or less chance of wet grass. A stronger trough by Monday may come about, though exact timing for rain remains in doubt. Onset of moisture shifts later each day, keeping the pleasant weather in play. More certainty will come in time, to be sure; for now the finer details remain obscure.

Aviation

VFR through the TAF period save for low probability river valley fog resulting in MVFR to LIFR visibility right after TAF issuance (12z-13z) and again Monday morning (11z-13z). Wind remains light with passing cirrus later today into tomorrow.

Outlook... High pressure ensures VFR and dry weather through at least Thursday with rising temperature and increasing cirrus reducing morning river valley fog risk.
