Refer to figures.

The chart is valid at 0600 UTC, which is fairly relevant to the time stated in the question (0550 UTC) => we can assume that approximately the same conditions will exist.
Looking at the chart, we can see that Paris Airport (LFPO) is located just ahead of a warm front.
Ahead of a warm front, we can expect steady continuous moderate to heavy rain from overcast clouds (generally, Nimbostratus). Moderate to poor visibility can also be expected. Winds usually blowing from a southwesterly direction (evidenced by the isobars distribution of the chart).

The METAR which best describes the above conditions is:
23014KT 3000 +RA SCT008 OVC025 15/13 Q1004 NOSIG=

  • 23014KT = wind 230º at 14 kt
  • 3000 = visibility 3000 m
  • +RA = heavy rain
  • SCT008 = scattered clouds at 800 ft
  • OVC025 = overcast clouds at 2500 ft
Note: Thunderstorms and showers are normally associated with cold fronts, not a warm fronts.
